some one stupid like you are
Coal is Non-renewable. It takes many millions of years to form and so whilst it is actually being replaced as we use it, the rate of replacement is so slow that we cannot say that it renews itself.
None of these words are even real words, there-for they do not have meanings.
Ocean tides will continue as long as the earth, moon and sun exists.
Well i don't know but this is a guess:It's a good reneable source of energy
Unrenewable energy refers to energy sources that are finite and will eventually be depleted, such as fossil fuels like coal, oil, and natural gas. These sources cannot be replenished within a human lifespan and contribute to greenhouse gas emissions and climate change. Because of their limited supply, unrenewable energy sources are not sustainable for long-term use.
Non-renewable energy source means that the source will eventually run out and is not renewable.
The non-conventional sources of energy are: 1. Wind Energy advantages- non-polluting; low cost production of electricity once setup; safe and clean disadvantages- noise pollution; wind mills costly to setup; disturbs radio and T.V. reception; harmful to birds. 2. Solar Energy advantages- inexhaustible; non-polluting disadvantages- expensive; diffused source, so gets wasted. 3. Tidal Energy advantages- non-polluting; inexhaustible disadvantages- destroys wildlife habitat; difficult to harness 4. Nuclear energy advantages- Emits large amount of energy disadvantages- generates radioactive waste; expensive 5. Bio Gas advantages- low cost; easy to operate; makes use of bio waste disadvantages- causes green house effect 6. Geothermal Energy advantages- clean Eco friendly and always available disadvantages- located far away from cities and so costly to transport the electricity
