What are characteristics of renewable energy and characteristics of nonrenewable energy?

Answer 1

Renewable energy:

• comes from the sun, the wind, the waves and the heat deep down in the earth
• is free
• keeps coming back next day even if you use as much as you can today
• doesn't cause pollution
• doesn't emit carbon dioxide, a greenhouse gas

Non-renewable energy:

• comes from coal, oil and natural gas
• won't last for ever
• gives off carbon dioxide when burns, and other polluting chemicals
• contributes to greenhouse gas in the atmosphere, increasing global warming
  

Answer 2

Renewable resources like wind power, solar power, wave and tidal power, hydro power, ocean thermal power and geothermal power are very attractive as energy sources.

• No greenhouse gas emissions
  
• No polluting emissions of any kind
• No costs for buying or transporting the fuel
• Unlimited supplies of the fuel.

Answer 3

Renewable energy comes from sources that are naturally replenished, such as sunlight, wind, and water. It is sustainable, reduces greenhouse gas emissions, and has lower environmental impacts. Nonrenewable energy, on the other hand, comes from finite resources like fossil fuels and nuclear energy. It is finite, contributes to climate change, and can cause environmental damage through extraction and use.

Answer 4

Several characteristics are common to renewable energy resources. One is that they are generally all-natural, with examples including water, wind and electricity.
