Read about the benefits of renewable energy and the different types of renewable energy. In fact, ocean energy comes from a number of sources. In addition. Renewable sources of energy are the ones which can be generated continuously in nature and are inexhaustible. These are the top 10 energy. From the late 's until today, fossil fuels—coal, petroleum, and natural gas—have been the major sources of energy. Hydropower and solid biomass were the most used renewable energy resources until the s. Since then, the shares of U.S. energy consumption from biofuels, solar, and wind energy have increased.

Hydropower is the most common form of alternative energy used around the world.


Need for Sustainable Energy During ancient times, wood, timber and waste products were the sustainable energy sources major energy sources. In short, biomass was the only way to get energy.

When more technology was developed, fossil fuels like coaloil and natural gas were discovered. Fossil fuels proved boom to the mankind as they were widely available and could be harnessed easily.

When these fossil fuels were started using extensively by all the countries across the globe, they led to degradation of environment. Coal and oil are two of the major sources that produce large amount of carbon dioxide in the air.

This led to increase in global warming. sustainable energy sources


Also, few countries have hold on these valuable products which led to the rise in prices of these fuels. Now, sustainable energy sources rising prices, increasing air pollution and risk of getting expired soon forced scientists to look out for some alternative or renewable energy sources.

Renewable energy

Second-generation technologies[ edit ] Wind power: The challenge is to broaden the market base for continued growth worldwide. Strategic deployment in one country not only reduces technology costs for users there, but also for those in other countries, contributing to overall cost reductions and performance improvement.

The systems may sustainable energy sources used to heat domestic hot water, swimming pool water, or for space heating. Energy received from the sun by the earth is that of electromagnetic radiation.

Top 10 Renewable Energy Sources

Light ranges of visible, infrared, ultraviolet, x-rays, and radio waves received by the earth through solar energy. The highest power of radiation comes from visible light.


Solar power is complicated due to changes in seasons and from day to night. Cloud cover can also add to complications of solar energy, and not all radiation from the sun reaches earth because it is sustainable energy sources and dispersed due to clouds and gases within the earth's atmospheres.

At the end ofworldwide wind farm capacity wasmegawatts MWrepresenting an increase of Nevada Solar One is another 64MW plant which has recently opened.

To compensate for this characteristic, it is common to pair their production with already existing hydroelectricity or natural gas generation. In regions where this isn't available, wind and solar can be paired with significantly more expensive pumped-storage hydroelectricity.

Information on pump, California Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar caneand ethanol now provides 18 percent of the country's automotive fuel.

As a result of this, together with the exploitation of domestic deep water oil sources, Sustainable energy sources, which years ago had to import a large share of the petroleum needed for domestic consumption, recently reached complete self-sufficiency in oil.

By mid, there were approximately six million Ecompatible vehicles on U. Third-generation technologies are not yet widely demonstrated or commercialised. These newest technologies include advanced biomass gasificationbiorefinery technologies, solar thermal power stations, hot dry rock geothermal energy and ocean energy.

Ethanol takes up a large percentage of "Clean Energy Use" when in sustainable energy sources, it is still debatable whether ethanol should be considered sustainable energy sources a "Clean Energy.
