The Costs and Benefits Between Solar and Wind Energy

Wind energy Vs Solar energy

The costs and benefits between solar and wind energy are very subjective. There are necessarily three factors that determine the economics: capitol costs, operating and maintenance costs and fuel costs.These must be taken into consideration when comparing renewable energy sources with conventional energy sources as well as when comparing one form with the other. Interestingly enough, the cost of renewable energy is enjoying an inherent decreasing cost curve while non-renewable sources are increasing in cost. Generally speaking, costs for photovoltaic and concentrating solar power (CSP) produced energy are higher in comparison to overall wind energy costs. Incidentally, the costs of wind versus nuclear, coal and natural gas are comparable.

There is an increase in the cost of renewable energy when you consider the costs associated with connecting it to the infrastructure that currently exists. Variability in things such as weather, the load demand, and material costs affect the costs and benefits between solar and wind energy. In the time between 2004 and 2008 the two industries experienced a massive increase in productivity. Solar photovoltaic energy production went up more than six hundred percent. Wind powered energy production increased by two-hundred percent in that time. Solar heating and bio-diesel production saw significant increases during that time also. Wind power became established globally between 1996 and 2008. By this year, world wide wind farm capacity reached almost 158,000 megawatts. This shows an increase of thirty-one percent in the last year and accounts for one point three percent of the global electricity consumed. » Read more: The Costs and Benefits Between Solar and Wind Energy

Biomass Renewable Energy – The Sun’s Energy in Organic Form

Biomass Renewable Energy

The words biomass and renewable energy would seem like entirely different ones without any sort of relation between them. Just imagine – the organic waste materials generated as a result of decayed plant waste on side and renewable energy on the other? But the fact is biomass is a large reservoir of solar energy trapped within it as a result of photosynthetic activities in plants, which if tapped out in the right way, can be a natural source of energy.

Renewable energy, as the term suggests, is the energy derived from natural sources like sun, water, organic waste, wind, tides etc which can be replenished by nature. Such energy sources can never get exhausted at any point in time as in the case or non renewable energy sources like fossil fuels.

Apart from plant wastes, other sources of biomass include wood shavings, algae, aquatic plants and residues, cow dung, disposable garbage, sewage wastes, corncobs etc. For it to be used as an energy source, biomass must be converted to energy so that so that it can meet a sizeable percentage of the country’s demand for fuel. » Read more: Biomass Renewable Energy – The Sun’s Energy in Organic Form

Renewable Energy Today

November 19th, 2011 by blinks No comments »

The world has experienced a history of countless energy crises. These crises were triggered by natural calamities, political crisis and war. However, most of the energy crises we are experiencing lately are caused by continues global increase in petroleum demand, coupled with our ever decreasing fossil fuel resources. Fossil fuel has been our main source of energy for a long time. In fact, it contributes as much as 75% of our total energy source, with oil coal and natural gas combined. Only a small fraction comes from renewable energy source.

Among several renewable energy sources, hydroelectricity makes up more than half the energy being produced from renewable energy source. Utilizing the waters energy to generate electricity is not yet feasible for small scale application, although it has already been used successful for generating electricity in large scale. Hydroelectric plants are located near dams to utilize bodies of water such as lakes and rivers. Other renewable energy sources widely used today are solar power, bio-fuel, geothermal and wind. » Read more: Renewable Energy Today
