Every day, the world uses 93 million barrels of oil. Not only does this pollute the earth, but we’re running out of resources. Hydropower is the world’s oldest and most widely used renewable energy source but, what exactly is it?

And what the US election means for climate change.
Watch more 2020 election explainers at http://vox.com/ElectionVideos
All of recorded human history has happened during a period in which the average global temperature didn’t change by more than 1 degree Celsius. But the burning of fossil fuels has triggered a temperature rise projected to exceed 3 degrees by the end of the century. It will be catastrophic. But it can be avoided if we massively scale back the burning of fossil fuels.
The US isn’t the biggest emitter of carbon dioxide in the world, but it’s emitted more carbon dioxide in total than any other country. So the US has an important role to play in global decarbonization; the world basically can’t get there without the US’s full participation. But the current US president doesn’t have any plans to do that. His Democratic challenger in the 2020 election, Joe Biden, does.
Biden’s plan is ambitious: Its goal is to completely transition the US to clean energy by 2050. But his plan doesn’t get into the details of exactly how that will happen. For that, we talked to physicist and engineer Saul Griffith, who took us through his incredibly detailed road map for how the US could actually walk away from fossil fuels in the next 30 years.
This was the first in our series of 2020 election explainers, all based on viewer suggestions. Watch the others, which cover the stakes of the election on:

16 Inventions Getting Us Off Fossil Fuels Video Rating: / 5
Educational video for children to learn what renewable energy source are, which are their main properties and what types of energies exist. The sun, the wind, the power of water or the inner core heat of the Earth are examples of renewable energy sources. These energy resources are produced naturally and for this reason they are not depleted. In this video, children will find out what is sunlight energy, eolic energy, tidal wave energy, hydraulic energy and geothermal energy. Some of the many advantages of renewable energy are that they are environmentally friendly, replenish naturally and are safer because they don’t generate toxic waste. Some of the drawbacks would be the lack of resources and natural phenomena in certain areas. Excellent resource for elementary school education.
