They are not completely problem free but they produce much less pollution and fewer greenhouse gases and by definition will not run out.
Consequences of renewable energy resources.
Renewable energy sources wind solar biomass hydroelectric geothermal etc are generally thought of as harmless but this doesn t mean they have no environmental consequences at all.
Nearly a third of the earth s electricity will come from renewables by 2024 according to the international energy agency.
As a result renewable energy prices can be very stable over time.
Conventional energy source based on coal gas and oil are very much helpful for the improvement in the economy of a country but on the other hand some bad impacts of these resources in the environment have bound us to use these resources within some limit and turned our thinking toward the renewable energy resources.
Renewable energy usable energy derived from replenishable sources such as the sun solar energy wind wind power rivers hydroelectric power hot springs geothermal energy tides tidal power and biomass biofuels.
The social environmental and economical problems can be omitted by use.
Fossil fuels coal oil and natural gas do substantially more harm than renewable energy sources by most measures including air and water pollution damage to public health wildlife and habitat loss water use land use and global warming emissions.
Although renewable facilities require upfront investments to build they can then operate at very low cost for most clean energy technologies the fuel is free.
Here are our main sources of renewable energy.
Renewable energy resources offer cleaner alternatives to fossil fuels.
Moreover the costs of renewable energy technologies have declined steadily and are projected to drop even more.
All energy sources have some impact on our environment.
Several forms have become price competitive with energy derived from fossil fuels.
