renewable energy short note
Renewable and nonrenewable energy sources
Renewable energy sources are those that are naturally replenished on a relatively short timescale. Renewable energy sources include solar, wind, hydropower, geothermal energy, and biomass fuels. These energy sources are sustainable and generate fewer greenhouse gas emissions than fossil fuels. Renewable and nonrenewable energy sources.
Solar energy | Definition, Uses, Advantages, & Facts | Britannica
The potential for solar energy to be harnessed as solar power is enormous, since about 200,000 times the world''s total daily electric-generating capacity is received by Earth every day in the form of solar energy. Unfortunately, though solar energy itself is free, the high cost of its collection, conversion, and storage still limits its …
