"This animation deals with the topics of biodiversity and climate change. It lays out the main effects of climate change, i.e. the strengthening of the natural greenhouse effect phenomenon that has been caused by our way of life, and the unprecedented speeding up of rises in temperature compared with the natural periods of warming that have occurred in the past. It also looks at the main consequences of these changes."

What does the future hold for the world's largest renewable energy source, hydropower? Hydropower is an incredibly old source of energy, tracing its usage back to the watermills that have been a staple of civilisations since ancient times. Today, it is the largest source of renewable energy in the world, with an installed capacity of over 1126GW in 2018. Hydropower is particularly prominent in China, where the world's largest power station Three Gorges power plant in Hubei province produces 22.5GW. Other massive projects also dot the country, including the Xilodu (12.3GW) and Longtan (6.3GW) dams.

The perennial argument for maintaining significant fossil fuel capacity is this: when the wind doesn't blow, and the sun doesn't shine, and the mercury drops low enough that the whole country simultaneously dials up the thermostat, then renewables on their own are not enough to keep the lights on

Electricity has begun to flow at Hornsea 1, a wind array that will become the world's biggest offshore wind farm off the coast of the UK. This milestone makes the UK's offshore wind sector arguably the best in the world, and with significant investment recently announced it looks set to maintain that position.
