A) Define renewable and non-renewable resources?

Question

b) Describe in detail non-conventional renewable sources of energy available to us.

Answer 1

Here's a good non-conventional renewable energy source: Solar Concentrator power. Basically you get huge mirrors to heat water and generate electricity in the same way as a 'conventional' source like fossil fuels and nukes (which, by the way, are NOT renewable!!!).

Also you should not confuse renewable with environmentally friendly or even sustainable. For example corn-derived ethanol is 'renewable' but is causing massive environmental and social damage. Also HE dams are really damaging too.

You should do your own homework though ;)

Answer 2

Renewable resources are resources that are renewed quickly enough to be replenished naturally, such as sunlight or wind. Non-renewable resources are resources that take many years to replace, such as coal, fossil fuels, and natural gas.

Answer 3

Renewable resources are those resources which can be used again and again and will not be finished eg :- sunlight,air etc.

non renewable resources are those resources which cannot be used again and again and will be finished after a period of time if used continuously. eg:- Fossil fuels like coal and petroleum.

Answer 4

Renewable resources can be replaced, in time. Non-renewables can't. Now, finish your own homework.

Answer 5

Renewable = powered by the sun in our current time period.  Examples are windmills, hydroelectric, solar cells, wood, corn, ocean waves, etc.

Non-renewable = energy created long ago and not replaced.  Examples are coal, oil, uranium.
