action of of government to stop transitioning the world to cleaner and cheaper sources of energy such as solar power and that issue is no more important than than here in africa way gone it's very slowly there's a giant need for cheaper more sustainable sources of energy well there's people living in apartments in new york and london who would love to other decide a panel but don't hurry to put it on and freeze and exchange dot com people are now other side panel in the sunniest places on earth so it's basically a revenue split so the sun shine hits the solar panel and the school gets some of that energy to offset their cost now they're they've. comes solar power and then anybody who puts as little as 10 bucks into financing those panels gets part of the revenue they get at david and in the form of because that goes right to their decline wallet and suffer the investor who is participating in this scheme they're turning sunshine into crypto currency and typically and it goes right into the wallet and it's happening in south africa how has the project scaled over the past 2 years you've done a

is researching the topic of solar energy. altamont of course on the moon we can't just plug our devices into sockets and we have to consider what kind of resources are available for producing energy there are no rivers there's no wind on the moon and there's no atmosphere if you will what is available is sunlight and it's better than on earth because it is not weakened by the atmosphere but from. your other schleppy wants to produce mirrors to create energy his experiment is also about how to use lunar regolith. fortas off we'll have the materials we've brought with us and there's this basaltic samples but what we can build out of basaltic sand is relatively simple bricks or walls by heating the material or baking what if we can go one step further and produced results a glass from the material. schleppy uses an ordinary microwave oven to make glass from the moon sand simulant. he grinds the molten regolith which is turned into glass as smoothly as possible so huge the glass brick still needs a reflective surface. this is made

within the renewable energy mix however the coming years will see some considerable strides in the solar energy sector but the transition towards clean energy does not inevitably suggest a simultaneous phasing out of the country's dependence on fossil fuels. now it's very difficult for you nor the government or even for the private shared very dependence on fossil fuels in dark regard what we have to do is we have to take over the graduated approach wherein we bring the renewables in in a more manner and we phase out fossil fuels in a manner where you know your economic targets and the lord know in our expectations of the industry are also you know taken care of but at the same time you are not kind of. disrupting the energy markets. today india is producing the world's cheapest solar power since 2010 set of course fell by 80 percent the most precipices decline of any country but continuing to meet the rising energy hunger of the population will require serious investment. we can all agree that fossil fuel based energy is one of the biggest causes of climate change but is valuable energy really

like we see the number they are now the largest producer of the solar energy and also wind turbine and also they have the highest selling number of the electric cars so in those regards we can still see that china is trying even though they have to step back a little bit so that they can ensure that their economy is not being affected so much by their amount of investment they put into the new energy sector. china like germany or the us coal regions bit may not want to let go of fossil fuels how big a factor. that factor really depends on how much they put into. modernizing household facilities so that the house houses regions can actually be connected to the new power projects that you know. for providing can actually ensure that. every household so in that regard we haven't really seen enough of the modernization come into fruition yet the long way to go for china that. thank you very much thank you. the north stream 2 pipeline is nearing completion it's designed to bring gas from russia to germany many are critical of the project including the european commission the usa poland and

something that from the line really puts a focus on finding new ways to to create energy improving solar energy improving wind energy and that will also create jobs that's an important part of a message ok there's a lot of number of concessions in this agreement giving some nation states powers to go about how they they reach a climate neutrality on a national basis poland for example will be getting special rights because of its dependence on fossil fuels on coal 77 percent of the energy on coming from from coal. exactly and leaders were quite aware of that problem that it is particularly hard for some member states particularly hard for poland to achieve these targets for the czech republic for instance it's a little bit easier because they have nuclear power plants and the czech prime minister also was keen to mention that nuclear has been put into that tax of putting some more legitimacy on a carbon neutral about rather foot from from the perspective from the others member states problematic energy source now the compensation will be here the key issue regarding regarding poland because eve

first extract carbon dioxide from the atmosphere known as carbon dioxide removal and 2nd reflect solar energy to prevent further heating called solar radiation management let's start with number one. a whole range of measures are being discussed on the one hand things like reforestation. trees absorb c o 2 from the atmosphere as they live and grow and when for 3rd preserved they can act as a carbon sink. and then there's the high tech version of that technology that would suck the o 2 out of the air like an artificial tree that c o 2 would need to be stored somewhere and for that we'd use geological storage. that's the big problem where to put the c o 21 idea is to store it underground. small test facilities already exist but there are concerns this music would have posted the risk or what people might worry about is that this. c o 2 might escape not necessarily in huge amounts but enough to negate the mitigating effect effect recent studies suggest that this is a fairly small risk. when it comes to solar geo engineering there are also various ideas under discussion the most common one involv

can we build solar energy in the desert? yes, i think so, but let's put them in places that are smarter. lovich: there is broad support in the public for protecting wildlife, and there is broad support for clean, renewable energy. what we should be looking for are ways to maximize both, and i thinink with resear, we're going to be able to develop some recomommendations r land managers to consider for mitigating the effects of renewable energy development on the tortoise for the benefit of society and for the wildlife resource. narrator: today much is being done for the desert tortoise. 6.4 million acres in 4 states have been designated as critical habitat. the erection of an 18-inch tortoise-proof fence along highways has reduced tortoise road kill by up to 75%. and the use of raven-proof trash lids in public areas has reduced foraging. the desert tortoise recovery plan includes research into habitat restoration, behavior studies, habitat mapping, and laland usage studis that may allow for better integration of both wildlife
