Renewable energy test questions - BBC Bitesize.
Renewable energy is derived from resources that are replenished naturally on a human timescale. Such resources include biomass, geothermal heat, sunlight, water, and wind. All of these sources have their strengths and weaknesses.
The energy is harnessed by a shaft inside the turbine that makes electrical energy and converts the electricity into the correct voltage for the local network. A lot of your top energy questions are about renewable energy sources and how they work. If you're thinking about switching to renewable energy at home, check out our guide to solar panels.

Renewable energy is generated from natural resources such as the sun, wind, and water, using technology which ensures that the energy stores are naturally replenished. Instead of buying all of your energy from suppliers, you can install renewables technology (also called micro generation and low-carbon technology) to generate your own.
Sources of Energy: A Comparison Turning toward cleaner energy sources means factoring in economic and energy needs alongside environmental ones. A man rides a motorcycle carrying his children along the top of a dam, which is flooded by an overflowing river near the Junyue township of Pengzhou, in the Sichuan province of China, on September 12.
Finally, several future energy scenarios are analysed to show how combinations of renewable energy sources and technologies could provide a major share of global energy needs.

Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants).
