currently, it has few competitors, solar energy accounts for one 3rd of the electricity generated from renewables in the u. it's the fastest growing sauce, but when the sunlight vanishes, there are hardly options to make it available at a later time as needed. the most widespread solution is battery storage. in the west of spain, energy giant ebert rolla uses lithium ion batteries is doubling the blender for this solar car and in the storage system will provide energy to $20000.00 homes every year when i when will avoid the emission of $12000.00 tons of c o 2 at the end, but it is the site manager over. so the parks construction, the install system, stores excess power that can be fed back into the grid when it is needed. the lithium batteries are locked away in these racks. we were not allowed to film them on the inside. within 3 hours, the batteries are fully charged. the energy is then used over the course of the day at times when there is higher demand or nor sun,

or going grandma said unable guarded it by these are times of expansion and the discovery of new storage technologies on handle it. but some technologies are developing in farsi hayes for oil in denver. we're in a little bit of that. so we'll have more storage systems in the near future and on the market on an industrial level and, and medically, is there any reading the freon, the batteries on the store power for limited time. and lithium is also in high demand for other green technologies. he kind of tech artega is convinced that lithium will soon be rendered obsolete by his team's method that uses limestone to store solar power. rather, you have to leave your whole magnificat lithium batteries, a magnificent who have great potential, very high performance out of you. lack of these are the lithia but lithium is an extremely limited resource, can only be found in very few locations in the world. i mean thing that for unit will look a little. the engineers hope that their storage method will be trialed at

a real plant in the next 3 years. if successful, the innovation could be brought to market, which by on, from storing renewable energy is the most important step in the fight against climate change. only include one or 2 and the clock is ticking, capturing the power of the sun is set to be a key step on the path to success. singapore is warming up faster than the rest of the world. and climate change isn't the only reason. it's densely built and wagman traps heat and air conditioning only compounds the problem . the need to keep cool has prompted the city to embrace innovative green solutions . ah, it's hot and humid in singapore all year round in temperatures reached $32.00 degrees and above dean. and to relieve his cap inside the small,

very refreshing 20 degrees demolish school by to raul's largest on the ground ag edition. located 25 meters below ground is the district cooling netbook, the 2nd of its kind and sink down here, water is chilled and piped out to 27 buildings. to keep them cool. the show size of the plant makes it so efficient with the ship. lincoln, the chief up to 40 percent in terms of energy savings. this is equivalent to powering 23003 room apartments for you. so this energy saved and also translated to carbon savings, which he saw reduction or removing $10000.00 cos off all routes every year. but this is how conventional air conditioning looks like. and singapore is

a back alley, in a historic part of the city, with hundreds of air conditioners. each machine is powered by fossil fuel and releases waste heat into the alleys and out to the city. it's a vicious cycle with global warming and heat rates, living without acquisition, it is tough, but more air conditioners, more waste heat meter, to the environment. samples founding prime minister leak when you was sick that the air conditioner to greatest intervention of the 20th century. we corneo wanted to mixing a ball of very hospitable and very comfortable for our uno american investors. we jokingly call it little america. and every building is fully i condition. what were sacrificed, taking to ask was a development of architecture suitable for the local climate. so when the weather

is good, we should be able to open up the building when the weather is hot and humid because it switch on the corner. so you so optional use of a condition rather been an absolute necessity. the challenge lou tropical architects is how do you desire a building like that? now some tropical skyscrapers have been built. this hotel is one example the i used to my idea, an architect from the cooling of our research project explains. this building uses of practical greenery that cover it's almost the entire facade of the building. and by having the figuration around the building, it can reduce the surface temperature. in fact, in our study, we found out that by having at least friendly test practical greenery in front of your building, it carried yourself as them for terabyte 5 degrees celsius. sample. as new as

public housing project, kona is where many solutions come together with district cooling party powered by to sun electric vehicles, charging stations, bicycle lanes of and farms, and we'll talk gardens. this is a look into what singapore could be like in the future. a more sustainable city, adapt it to its climate change challenges, noisy and polluting traffic besets all cities like of clique. what would they look like if bicycles were given the right of which we met a german designer who dare to dream? these kind of nations shows what the halston plants and hamburg would look like. if all the cars and traffic signs were gone, making room for trees and grass. it could be a square of paradise for cyclists and pedestrians. but it actually looks like

this, much to the displeasure of hamburg graphic designer yon kaminsky. he would like to see fundamental changes, which is why he began making animations of how he believed streets should be been on fun, out of quicksilver getting the project. got started with the beginning of the cobit pandemic, marson, which i looked around and thought of. i don't want to just sit and wait for the changes we need, like i want to contribute read august i. and as a visual designer, i can change urban spaces up or before and on. young kaminsky thinks gray streets and dreary squares should be transformed around the world. or at least in animations to start like here in new york city. and in belgium's capital russell's and germany's capital berlin, the graphic designer, launch social media accounts under the name utopia for bicyclist. as paul may up

plots was thought we need more space for bikes and more bicycles so that their genius can take effect for some follicle. their low emissions, the some i didn't take up little space compared to other modes of transportation plots and for light and can be used for many things on this is phyllis, auto ions at spot. yon commence gaines vision is already reality in germany's neighbor, the netherlands, for example, in the countries 4th largest city group traced where $125000.00 people cycle daily, whatever the, whether that's more than a 3rd of the city's population. chris brantley works for a network that advocates greater use of bicycles. he spends much of his time on the frame bush the most heavily traveled bicycle path, given that balanced in used to be

a multi lane road with traffic like the one is found in all cities. unfortunately, a lot of cities cycling is still just for the fit and the brave and the really risk taller and people that are willing to rub shoulders with motor vehicles. but that's not the vast majority of people that live in that city they want. ah, to be able to tune out and, and just enjoy their can you and, and when you provide safe sagat separated space for cycling. you're going to track more of those, those casual users. in 2019 the world's biggest parking garage for bicycles opened and you thrashed displays. tell cyclists of any spaces are free up to 12500 bike riders can park here right next to the main station. in fact, the country has become known for its bike, friendly and aesthetically pleasing solutions, such as the toughness skippers, bridge, which passes over the roof of a school and connects to neighborhoods is just so much more convenient to travel

around the city on a bike. and so much quicker and more fun hamburg is still far from being a cyclists paradise. but young kaminsky hopes to at least bring attention to urban mobility questions. daughters does is false pressure by pushing forward. i'm creating opportunities for debate worse. so one way or the other, i'm provoking some kind of rethinking of the issue and also on those young kaminsky hopes his utopias. mo remained purely digital, and that not only hamburg, but metropolis is like paris will become bicycle paradise's, much like the once he designs and animates cars completely gone and only bicycles on our streets. i'm not so sure about that turning to reality it, but it is true let we will need new and innovative vessel thing to, to deal with problems of the future. especially with 2 out of every 3 people

expected to live in cities by 2050, according to the un alina with that and see you again next week from all of us in india and germany. good bye. and thanks for watching ah, [000:00:00;00]
