welcome to global lessons, the gps road map for powering america. i'm fareed saturdza kasaturday . will at a recent talk at the ted conference, bill gates let us in on a secret, if he could have anything, this is what the world's richest man wants, an energy source that is cheaper than coal and has zero carbon dioxide emissions. he said this would be the best thing for the human race more than anything he could imagine. why does gates think that? because he knows the world is going to consume a lot more energy ahead. for example, in the next decade, the number of cars on the road will double from 1 billion to 2 billion. overall, we'll consume 50% more
5:01 pm
energy. why? well, americans and our suvs are partly to blame, but really, it's about the rise of the rest. the world will add 1 billion people over the next two decades. if these people in fast growing countries like china and india have dreams like the american dream, houses, cars, tvs, big macs, then, as the "new york times"s columnist tom freedman says, we will need another planet. today we power our lives with fossil fuels. oil, coal and natural gas provide 80% of our energy. but do we have enough energy to keep growing at this pace? and are we harming the ecosystem in which we live? already sea levels are rising the arctic ice caps are melting. and scientists projections about climate change are becoming more alarming. that's why bill gates makes his wish for energy that is cheap and clean. in this hour and in a "time"
5:02 pm
magazine essay, we're going to see who's doing best at energy production around the world. we'll look at technologies of the future and best practices of today. we'll go to a country that gets 75% of its electricity from a source that emits zero carbon dioxide and we'll introduce a new energy that's cheap, cleaner than coal and right in our own backyards. but first i'll take you to a country that was almost completely dependent on energy from the middle east 40 years ago. now this nation is totally energy independent. how did they do it? let's find out.it
5:03 pm
>> in 1973, denmark was in big trouble. the yom kippur war led to an oil embargo and the days when most of europe was dependent on foreign energies. so they banned driving on sundays and told people to turn off their lights. in the americas as well, the 1970s brought a sense of crisis. >> i am tonight setting a clear goal for the energy policy of the united states. >> president jimmy carter encouraged conservation and installed solar panels on the roof of the white house. but those panels eventually came down and our resolve to go green faded. meanwhile, denmark doubled down on green energy, and now, incredibly, they are completely energy independent. they were helped greatly after discovering oil and gas in the north sea. author of "that used to be us" tells the story of denmark in "hot flat and crowded," his book about going green.
5:04 pm
what was the striking thing about denmark? >> little denmark had produced a whole set of export industries around clean, renewable energy. >> after the oil crisis, the danish government subsidized renewable energy and levied big taxes on gasoline and fossil fuel. gasoline costs about $8 a gallon these days. did all of that kill economic growth? no. since 1973, denmark's economy has slightly outpaced the economies that now make up the euro zone. what you get is enormous innovation because all your industries produce are you newable energy that can sell in their marketplace. once they do it for little denmark, they looked around the world and said well, we can kill it in america and we can kill it in china and that's why two of the biggest energy companies in the world for wind and biofuels are danish.
5:05 pm
>> one danish powerhouse is vestis, the builder of almost one-fifth of the wind turbine capacity. they produced green jobs before they were trendy. >> we learned that energy dependence is something you should take very, very seriously. vestis' ceo learned that the danes get almost 30% of their electricity from the wind, more than any other developed nation. by 2020, they pledge to get half of their electricity from wind power. and by 2050, they promise to be completely fossil fuel-free. >> it's not about what is possible from an ecological point of view, it's all down to leadership and determination.
5:06 pm
>> fanso is a sign of what's possible. a sleepy island between the sea and the ball tick sea where you might see as many cows as people. but don't let the rustic setting fool you, the island is on the cutting edge of energy efficiency. all of its electricity comes from the wind and overall samso has a negative carbon footprint. farmers like this man are clean energy entrepreneurs, owning shares of the island's wind turbines. >> the wind turbines on the sea they produce 18 million kilo watt so that's the biggest export from the island that's electricity. >> dick engel says the u.s. could be a wind powerhouse, too. think of those windy prairies in the great plains. >> when i discover that these resources are not being harvested, i really get amazed
5:07 pm
because, to me, that would be like going for instance to saudi arabia and not drill for oil. >> but despite its potential, the concept of wind power isn't blowing everyone away. >> fundamentally, wind is still more expensive. >> denmark's author of "the skeptical environmentalist" says that the danes' energy prices are the highest in the world. he also points out that vestis has run into trouble, it plans to cut out 4 million jobs in 2012. including one-fifth of its u.s. workforce. and wind power overall, he points out is still more expensive than the cheapest fossil fuels. >> as long as it's not competitive, i still think we should say, let's invest more in getting the next generations of wind turbines to be cheaper rather than putting up lots and lots of them that we know are inefficient right now. >> but people say the only way you get the cost curve down is deploying large amounts of
5:08 pm
existing energy for scale. >> it's still scale, but it's expensive even after we produce lots of it. >> another big challenge, storing wind power, to use when the wind isn't blowing. in fact, all. world's current battery capacity can store only ten minutes' worth of the world's annual energy demand, according to bill gates. one idea? take the excess energy that you can't store from the wind turbines and use it to charge the batteries for electric cars. one company called better place already has charging stations all over denmark connected to the grid where you can swap out your dead battery for a live one in just minutes. but with few electric cars on the road, that solution may take a while to catch on. denmark's wind driven approach to energy is compelling, but wind power can be intermittent, more expensive than fossil fuels and requires a big commitment.
5:09 pm
next, we'll look at another carbon-free technology with truly remarkable potential. [ male announcer ] citi turns 200 this year. in that time there've been some good days. and some difficult ones. but, through it all, we've persevered, supporting some of the biggest ideas in modern history. so why should our anniversary matter to you? because for 200 years, we've been helping ideas move from ambition to achievement. and the next great idea could be yours. ♪
5:12 pm
zero in 14 1/2 seconds, the sun will have emitted enough energy to power the earth for an entire day. here's another way to look at it, we could power the entire world if we covered less than 3% of the sahara desert with solar panels. the power of the sun is truly remarkable. and, surprisingly, no country is better an harnessing that power than a cloudy and cold land, germany. how did that happen? we went there to shed some light on the subject. may 25, 2012, was a historic day for germany and for the entire planet. at midday, solar panels in germany set a world record supplying one-third of the nation's electricity demand. germany is certainly not known for its sunshine, yet the nation boast's one-third of the entire world's solar capacity.
5:13 pm
>> there's no other country in the world that comes anywhere close to that level. >> dr. thomas knipe is the ceo of one of the world's leading energy companies, he says the nation's opinion about energy was changed by the soviet union's nuclear plant meltdown at chernobyl that affected many germans. >> i remember i was riding by bike as fast as i could to get home because there was a cloud coming and everyone told you not to get in the rain because there were toxic particles in it. >> in the wake of the disaster, political groups like the green party gained potential. >> they took on environmental issues in their program. >> one of the key measures parliament passed was the so-called feed-in tariff. if you were a german hoerm owner
5:14 pm
with solar panels on your roof, you can feed your energy back into the grid and your power company is required to pay you for that energy for 20 years. was it after the feed-in tariffs were enacted that solar really took off in germany? >> yes. germans, they doenl of don't install solar systems just for saving the world. they install them because you get a nice return on investment. >> since 2000, solar inslaingss in germany have jumped 600fold, providing a boon for families. >> solar returns in new jersey has exploded 600,000. and even for some suburban families. families like these who live outside of berlin. he gets about $3,000 every year for the energy that his rooftop panels feedback into the grid.
5:15 pm
in seven years he'll have made enough money to cover the cost of buying the panels. after that, it's all profit. >> we were made a profit, but that's not the main reason, the main reason is that we are independent in the future from all these huge energy costs. >> as solar has become more and more popular in germany, the cost has plummeted. and worldwide, it's the same story. >> over the last 20 years, with every doubling of capacity installed, the cost of solar has gone down 20%. and that has accelerated over the last two years. >> solar panels also have the advantage that you can put them where the energy is needed, say, in a new town or a remoting factory, without having to lay power lines. but solar energy has its critics. >> germany is definitely leading but it's not something they should be boastful about. >> critics point out that
5:16 pm
solar energy still provides only 5% of germany's electricity and less than 1% of its total energy. remember that world record day i told you about when solar provided a third of germany's electricity? that was a very sunny day. what's more, solar subsidies are blamed for driving up energy costs for non-solar customers. >> the problem is, in order to do all of these things, you need subsidies, you need taxes. people look at that and say, this is just going to produce lots of distortions or inefficiencies. >> that's right. they say, let's get rid of all of it, the oil depolice allowance, all the subsidies for coal and nuclear and let's let everyone compete. >> still, even in green-friendedly germany, solar subsidies have caused a political backlash. the main solar subsidy is being gradually phased out, but angela merkel made an unscheduled cut of around 30% last spring. some german solar companies have run into trouble in recent years, filing for bankruptcy. >> we have a consolidation phase
5:17 pm
right now in the industry. the quite frankly there isn't a single company that is making decent profits right now. >> one reason, chinese solar companies are oversupplying the market with cheaper panels helped by their own government subsidies. and even some of them are taking big losses. >> china has made solar energy so cheap, as cheap as tennis shoes and under shirts, basically. the fact is, germany is actually using so much more solar energy, but it may not be german companies that are benefitting from it. >> the potential for solar energy is huge, but it is still expensive, limited in scale and like wind, you still need some way to store it when the sun isn't shining. what about nuclear power? doesn't it solve all these problems? next, we'll visit a country that gets 75% of its electricity from nuclear, and it's never had a major accident.

one country with little access turned to nuclear energy before the 1973 oil crisis awakened the world. today, france generates 75% of its electricity by splitting apart atoms and it's no coincidence that france has cheap electricity, and as you'll see, the french are apparently so thoughtful, they even recycle their nuclear waste. on august 6, 1945, the world was by little boy. that was the code name for the first ever atomic weapon dropped on hiroshima and killing in the end more than 100,000 people. out of this terrible tragedy, an industry sprung up, one that has been surrounded in mystery and conflict. >> around nuclear, there is ideology and i would say even religious and there is a feeling that there is few people which are dealing with the life of the
5:23 pm
humanity. >> the head of generation and engineering for electricity to france, the state-owned utility company, thanks to nuclear energy, france makes $3 billion every year as the world's largest net exporter of electricity. >> the only mass way of producing electricity, whatever the season, the time, the hour in the world without producing co2 is nuclear. there is no other way. >> here a traditional french town on the normeden di coast, nuclear energy seems to be a part of life. that's just the way things are, says this retired roofer. >> translator: there are people who don't like it. it doesn't bother me. it's great. without them here, we'd be dead. >> dead because the nuclear sector is the biggest employer here.
5:24 pm
this may be old france, but this town also represents the future for french nuclear power. this is the site for the epr, the european pressurized reactor. a third generation reactor that edf says will be more powerful and safer than old models. of p we included a lot of new devices which came from feedback experience from three mile island accident, chernobyl accident, even now we include new devices to answer the fukushima accident. >> but the construction of this rethought reactor is running four years behind schedule and is set to cost almost twice its original budget. and, contrary to popular opinion, it's that cost problem, not safety, that's at the heart of the nuclear issue, says "new york times" columnist tom
5:25 pm
freedman. >> there are a lot of people in the nuclear industry that look at nuclear with suspicion. >> the only thing that is a fact is price. if you want to build a 1 gig awatt nuclear plant, it's at least a $10 billion proposition. that's really why it hasn't gone ahead. that said, i don't see how we get to scale without a nuclear component in our energy mix, and i think it can be done cleanly and safely. so i am not an opponent of nuclear energy. >> the day-to-day operating costs are low, and the french have streamlined up-front costs by using just seven design models to build their entire 58 reactor fleet. >> the key of the cost in industry is standardization. the edf program has been built at half of the cost german one and a third of the cost of the japanese one. >> the industry has used several
5:26 pm
plant designs and where we store our nuclear waste, france recycles it. >> so i'm authorized to go inside. >> this woman works for state-owned nuclear giant areva. once the spent fuel arrives here at the reprocessing plant, it is unloaded and cooled. >> the spent fuel is then cooled inside cooling bath and then put inside a basket. >> all of france's used fuel ends up in pools like this. >> what you see here are the baskets where the spent fuel is stored. in the spent fool, 96% of the material is recyclable. >> about 17% of france's electricity comes from reused nuclear fuel. before she can get to the storage facility where the non-recyclable parts of the fuel are, she passes through a radiation contamination check. >> it says that we had 0.1
5:27 pm
microsieverts. >> having only absorbed 1/500th the amount of radiation of a transatlantic flight, jordan makes it to the storage hole. >> under my both feet here, i have the equivalent quantity of what is left after one year of a production of a nuclear power plant. >> i wish we didn't have to have nuclear, in an ideal world i'd love to replace it with full renewables. but i worry if we shut all of this down what would happen on the price side. >> but shutting down is exactly what the new french administration has talked about doing. the socialist president francois hollande has promised to reduce france's share of nuclear from 75% to 50% by 2025. so far, only one of frances's reactors is set to be
5:28 pm
decommissioned. nuclear energy accounts for 20% of america's electricity production. if there's a future for nuclear power, as a constant carbon-free companion to renewables, it will look more like the french model and there are promising new technologies that might do much better than the french model with regard to safety, cost and waste. but they're still on the drawing board. coming up next, we'll explore what is the biggest energy revolution right now. and it's happening right here at home. we'll be right back.

we've traveled the world to see how other countries have focused on wind, solar and nuclear power. currently all those forms of energy have up sides and down sides. but what if we could innovate our way to a more effective energy technology right here at home? we may already have done that. down in louisiana, off the gulf of mexico, something strange is happening. a few years ago, as american natural gas supplies were dwindling a company called shanear energy built a facility to import liquid natural gas
5:33 pm
from other countries. now, just a few years later, it's converting the facility to export gas. so you build this terminal to import liquid natural gas. >> yes. >> a funny thing happens in the next few years. >> well, it wasn't so funny. >> it wasn't funny for the ceo of the company because his company almost went bankrupt. what happened? the low levels of natural gas production in america suddenly gave way to a boon, thanks to shale gas. how big is the shale gas revolution in america? >> it's st ae's stup fivingly l. in 2000, shale gas accounted for only 2% of all natural gas. in 2012, it accounts for 32%.
5:34 pm
that's because america happens to be the saudi arabia of shale gas with big shale deposits over much of the country. and here's the kicker. when you burn natural gas to produce energy, it emits roughly half as much greenhouse gas as coal. >> natural gas is the perfect complement to wind and solar. not only does it emit half as much co2 as coal, but you can just turn it on and off when the sun goes down or the wind stops blowing to make tremendous inroads in reducing our carbon emissions. >> in fact, we have already reduced emissions. in 2011, greenhouse gas emiss n emissions in the u.s. were 9% lower than 2007 levels. one reason was that demand for transportation fuel was down, but another major cause, according to the government, was our switch from coal to natural gas. in 2000, natural gas accounted
5:35 pm
for only 22% of the electricity we get from fossil fuels. compared to 73% for coal. through july of 2012, it accounted for 46%, and coal was down to 53%. that dramatic switch didn't happen because of our suddenly greener outlook on life. a main reason it happened is because natural gas now costs about the same as coal. >> fracking shows us if we get the price below, for instance, coal, everyone will adopt it. you will get a dramatic shift. you'll get reduction in co2 emissions because it's a greener alternative and you'll get cheaper prices. >> but there are definitely some downsides to shale gas and plenty of controversy. here's how fracing works, millions of gallons of water mixed with sand and chemicals is shot down a well as deep as 10,000 feet below ground.
5:36 pm
the water hits the shale with a alot of pressure, causing it to fracture and release natural gas back up the well. >> what you do with that water afterwards is very important. can you treat it? clean it again and reuse it? do you just leave it in pools lying around? do you inject it into the ground in ways that could cause earthquakes, which is a real problem? or seep into aquifers? >> another challenge? containing gas leaks during the extraction process, especially methane, which is a potent greenhouse gas. the oscar-nominated documentary gas lamp portrayed how people's water supplies became flammable. many of these allegations have been contested. for example, sometimes the gas that has ended up in people's water pipes comes from wells that they drilled in their backyards, not from fracing. but the epa is working on a comprehensive study of fracing, as it should. this is an industry that needs
5:37 pm
regulation. of. >> i think it's very important that we get a grand bargain between the environmental community and the natural gas industry that says, we're going to do this right. it's in the huge interest of the natural gas industry because if i turn on my tap and a flame comes out or i've got natural gas coming up my toilet, i'm telling you they will shut this industry down. >> that would be a shame for our economy. shale gas is cheap energy and cheap energy fuels growth, from lowering our heating bills to cutting the costs of shipping and making things. pricewaterhousecoopers says the shale gas boom could spark a manufacturing renaissance creating 1 million manufacturing jobs by 2025. and think about how cheap natural gas could lower carbon emissions in china and india, where they are building four coal-fired power plants a week with disastrous environmental effects, not to mention the
5:38 pm
thousands of people who die because of coal mining. >> what really matters is what china and india does. they want more energy and they want it cheaper. so what we have to make sure is that we focus on innovation to make green energy sources so cheap they will switch. we have shown the way through the fracing of gas, but we still need to move further. we need to make green energy, solar panels, wind turbines, even cheaper. once they become cheaper than fossil fulz, everyone will buy them. >> once the natural gas terminal is up and running, they'll be able to move energy to china and india for a good profit and create jobs here at home. we've shown you many different approaches to energy in this hour, but we're saving the best for last. next, we'll show you what is arguably the greenest, safest, and most profitable form of energy. this is something that tree huggers and ceos are both going to love.

i'm cnn meteorologist bonnie schneider with this update on hurricane sandy. this category 1 storm continues to work its way closer to the united states, already we're feeling impacts in terms of wind and very heavy rain across the coastal sections of the carolinas. the track shows a little more consensus in the computer models that the northwesterly turn will take place. landfall, though, is a little bit more difficult to predict,
5:43 pm
somewhere in the delmarva, possibly as far north as new york. meanwhile, this is a large storm that will impact so many people, millions of people, because of heavy rain that's expected, possibly six inches, ten inches or more in parts of virginia. and we're also looking at the storm bringing heavy rain to new england and to the great lakes as well because of its size and the speed. it's really going to slow down. heavy snow is expected in the mountains west virginia, that cold air is coming in right behind it. so watch out for a wintry event. and of course with the winds so strong, we are looking for the potential for power outages not just for the northeast but a large, expansive area. it's possible millions could be without power due to hurricane sandy and the strong wind that are working their way across this system. that's a look at this hurricane. i'm meteorologist bonnie schneider.

energy per unit pound than aluminum or steal so your cars are not only going to be lighter but they'll be safer. >> if hypercar sounds like science fiction to you, volkswagen and bmw will start producing their versions of hypercars next year. and it's not just cars. buildings can get a lot more energy efficient, too. if america's 120 million buildings were a country, they would use more energy than every country in the world except for the united states and china. a lot of that comes from densely populated cities like new york where luvens helped retrofit the empire state building. >> we were able to get the 6,514 windows remanufactured on site into superwindows that let light through but block heat, and then combining that with better lights and office equipment and so on, cut the maximum cooling load by a third.

>> and all that energy savings also saved over $17 million. so no matter what your values are, aimry luvens argues, energy efficiency is simply a good deal. >> whether you care most about profits and jobs or about national security, you don't need to believe the climate science, let's just focus on outcomes, not motives, and then we can turn gridlock and conflict into a unifying solution to our energy challenge. >> we can't all turn our living rooms into tropical oasoases, b we can turn aimry luvens ideas into public mandates. big business makes big profits. it saves that goes straight to the bottom line. consider the impact that just two steps could have. one, move over to energy-efficient bulbs and appliances. a 1.8% reduction in our residential electricity use can

energy equivalent of the labor of 2,000 humans. another is a jet plane. it uses the energy equivalent of 700,000 humans. so the first thing to admit is that we need lots of energy. the second is to realize that, for the foreseeable future, we will be dependent on fossil fuels. in 2010, the u.s. got 83% of its energy from fossil fuels. in 2035, despite great increases in efficiency, the u.s. government says we will still get 77% of our energy from fossil fuels. that leads to a few conclusions. we need more renewable energy. today renewable energy gives us 10% of our electricity. by 2035, that will rise to 16%. we should try to move towards it faster. but even if we were to succeed,

we would still need to use fossil fuels for the majority of our energy needs. governments around the world, including the united states, have provided enormous help to the fossil fuel industry, in many ways, from building out the infrastructure it uses to protecting our supplies of oil from the middle east. even fracing but the way was developed with the help of the department of energy. so it's perfectly sensible to say government should provide support to the technologies of the future as well. that support should mainly go towards research that would lead to technological breakthroughs. but we should also help these nais ent industries, wind and solar, to achieve scale, just as we helped the computer industry in the 1950s and 1960s. but having done all of that, it is clear that we will still need fossil fuels for the majority of our energy for decades to come. that means choosing among them,

and when natural gas replaces coal, you end up with a win-win. it is cost competitive, and it emits half the carbon die ox will i'd emissions of coal. the conversation about fracing cannot take place without considering what would happen if we did not get that energy from shale gas. we would get it from coal, which is the dirtiest fossil fuel in existence. we were all expecting a technological revolution in energy now, and we got one. but not in renewables yet. rather in the extraction of hydro carbons. it allows us to extract mountains of natural gas. fracing should be studied carefully. it needs regulation. but we should also recognize that this might be the bridge fuel to our eventual goal -- cheap energy with zero emissions. finally, there is one area where we really should all be able to agree. energy efficiency.

it's a no-brainer. it saves money, and it involves no real sacrifice. when you go to a hotel in europe, chances are that, as you leave the room and take the hotel key out of its slot, the lights will go out. why can't we standardize that practice everywhere? an energy revolution would be great for the environment, but it would also be great for economic growth. energy permeates every of asp af our lives, even more so than something like information technology. and you can see what a huge impact the information revolution has had on economic growth. an energy revolution would be the next big thing we've all been looking for. you can read more of my thoughts in a"time" magazine essay. thank forz tuning in to this gps special. you can catch my regular show on sunday 10:00 a.m. and 1:00 p.m. eastern.
