in current scenario why the renewable sources of energy are more important than nonrenewable sources?
Answers
Renewable resources are important for a number of key reasons:
1. They don't further deplete non-renewable sources such as fossil fuels.
One day, obtainable fossil fuel resources will run out. If we aren't ready with alternative fuel supplies by then, the human populations of this planet will suffer (no fuel for heating means people will get cold; no fuel for power generation means our entire global infrastructure will fail - virtually everything runs on electricity; the inability to process food means people not living directly off the land will starve).
2. They don't usually release unsustainable levels of carbon dioxide and other greenhouse gases into the atmosphere.
Man made climate change is almost universally agreed to be due to the uncontrolled use of fossil fuels (coal, oil and natural gas) largely for heating, power generation and transportation, and because these fuels release carbon dioxide (CO2) gas into the atmosphere when burnt. In a nutshell, CO2 acts like a blanket, insulating the planet, and excessive concentrations allow less heat to escape into space than is generated on the surface from incident sunlight. The net effect is a gradual, global warming.
3. They don't place undue stress on the environment or indigenous populations.
An example of non-renewable timber production is that obtained from the logging of rainforests, which decimates the environment without giving back anything beneficial or conducive to its recovery.
hope it helps you!!
Non renewable sources of energy are getting depleted day by day. So their is a need of promotion of the use of renewable sources of energy to keep the non renewable sources of energy to be used in the future.
