2 · Solar and wind are popular renewable energy sources in the US right now. But which will take the lead in 2022? An expert weighs up the pros and cons.
CNN spoke with energy transition experts about the most reliable energy sources – and their challenges – to replace coal, oil and gas and halt the climate crisis.
But which type of renewable energy is the best? We''ve investigated the major ones – including solar power, wind power, and geothermal energy – further below. Read on to find out.
To reduce CO 2 emissions and local air pollution, the world needs to rapidly shift towards low-carbon sources of energy – nuclear and renewable technologies. Renewable energy will play a key role in decarbonizing our energy systems in the coming decades. But how rapidly is our production of renewable energy changing?
The world''s most relied-upon renewable energy source isn''t wind or sunlight, but water. Last year, the world''s hydropower capacity reached a record 1,308 gigawatts (to put this number in
The key insight is that they are all much, much safer than fossil fuels. Nuclear energy, for example, results in 99.9% fewer deaths than brown coal; 99.8% fewer than coal; 99.7% fewer than oil; and 97.6% fewer than gas. Wind and solar are just as safe.
2 · It''s possible to switch to a fully sustainable global energy landscape within the next 30 years, according to research. Greater geographical connectivity of solar, wind and hydro power, can reduce energy use and cut costs.
