so we took a year to design and build stella, the world s first solar powered family car and raced it 3,000 kilometres through the desert of australia, and that set us up for the next adventure, for lightyear, so a few years later after we finished our studies and we took the car all over the world and we had hoped to inspire the industry, to show that it is possible to build a car that drives only on the power of the sun and is efficient and lightweight, but it din t really happen so at some point we figured if we want to get this to the market, we will have to do it ourselves and that is when we founded lightyear, six years ago. and in this race that you took part in at the start of all of this, you re racing across the australian desert in a solar powered car. this is not vehiclesjust creeping along the desert for weeks on end is it? how fast do they go? 3,000 kilometres in about 5.5 days, average speed of 70 kilometres an hour, top speed around, it depends a bit

otezla. show more of you. welcome back, california li live , california reached a milestone this spring, producing enough renewable energy to meet demand, but as reported, there s a debate over who pays to maintain the grid. reporter: power of the sun is free. not the solar systems that harness it. and increasingly, there are financial winners and losers uc berkeley professor dorenstein studies the economics of renewable energy. all the data shows the customers putting in solar are dispro disproportionately wealthy, shifting costs on to those poorer than they are. homeowners have a lot of
broken promises on climate, says the un. some governments and business leaders are saying one thing but doing another. simply put, they are lying. and the results will be catastrophic. but there is some good news in today s report, so let s start there. the cost of renewable technologies wind turbines, solar panels, batteries have been falling far quicker than anyone expected. as a result, the world is rapidly building solar and wind plants. in fact, last year, 10% of global electricity was generated from renewables, according to a report last week. but, says the un, harnessing the power of the sun and the wind will not be enough. the report details how we ll also need to change the way we get around, what we eat, how efficient our homes and businesses are, how we farm, how we produce the goods we buy, how we move those goods around and how we protect the natural world. in short, pretty much everything has to change,
