Potential applications of renewable energy sources
The potential of renewable sources is massive as they are expected to meet world’s energy demand. Renewable energy sources are biomass, hydropower, geothermal, solar, wind and marine energies they can provide sustainable energy services, based on the use of routinely available, indigenous resources. The renewable resources such as biomass, wind, solar, hydropower, and geothermal can provide sustainable energy services, based on the use of routinely available, indigenous resources are attractive renewable fuel in utility boilers.
While price of gas continue to fluctuate a transition to renewables-based energy systems is looking increasingly likely as their costs decline. Solar and wind powers continue their rapid sales growth in the past 30 years. Due to this their capital costs and costs of electricity generated, and have continued to improve their performance characteristics while fossil fuel and renewable energy prices, and social and environmental costs are heading in opposite directions. The economic and policy methods needed to support the widespread dissemination and sustainable markets for renewable energy systems are evolving fast.
Renewable energy sources (RES) supply 14% of the total world energy demand. The future growth in the energy sector will be primarily in the new regime of renewable energy, and to some extent natural gas-based systems and the conventional oil and coal sources will then die out. These developments will innovate the market opportunity to emerge and promote renewable energy technologies but of course with the assistance of governmental and popular sentiment.
If develop further the RES can enhance diversity in energy supply markets that will lead to contribute in securing long term sustainable energy supplies. It can also help reducing local and global atmospheric emissions that will revive our dying planet. Lastly it will provide commercially attractive options to meet specific energy service needs, particularly in developing countries and rural areas helping to create new employment opportunities there. This is all because the renewables are the primary, domestic and clean or inexhaustible energy resources. And because they can be regrown there is no fear of loosing them years from now.
An example of renewable is the biofuels, one advantage of biofuel aside from it can be regrown is that it can offer environmental benefits such as lower carbon emissions and lower sulfur compared to first generation biofuel. It is then believed that biofuels could help meet the world’s future energy needs.
Other benefits are:
Power generation. Renewable energy provides 19% of electricity generation worldwide. Renewable power generators are spread across many countries, and wind power alone already provides a significant share of electricity in some areas
Heating. Solar hot watermakes an important contribution to renewable heat in many countries. Direct geothermal for heating is also growing rapidly.
Transport fuels. Renewable biofuels have contributed to a significant decline in oil consumption in many parts of the world. The 93 billion liters of biofuels produced worldwide in 2009 displaced the equivalent of an estimated 68 billion liters of gasoline, equal to about 5% of world gasoline production.
