Rabbi Yitzhak Miller Renewable Energy By Ghanendra Uprety.

International Energy Agency defines renewable (re-new-able) energy as the energy derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources such as sunlight, wind, rain, tides and geothermal heat.

Sun is the ultimate of all the source of energy. Renewable energy can be obtained from the same source for a long period of time without depleting a source. For example solar energy can be obtained continuous from the sun without depleting the source. This is in contrast to the non-renewable or commercial forms of energy such as oil and gas. The more they are extracted, the more will be the reduction in source.

A growing body of scientific evidences has demonstrated that the heavy reliance on fossil fuels or commercial form of energy is destabilizing the climate. Emission resulting from the combustion of fossil fuels such as coal, oil, and gases are responsible for the emission of Greenhouse gases. Green house gases (GHGs) in turn are responsible for heat imbalance of the earth resulting climate change. Climate change is the burning environmental issues. On the other hand, energy produced by renewable sources greatly reduces greenhouse gas emissions relative to energy produced from burning fossil fuels.

Global environmental concerns, the depletion of the earth’s finite resources and economic considerations are all incentives to interest consumers in renewable. Although renewable cannot yet replace all existing energy sources, they can supplement power generated by utilities and increase the diversity of our energy supply. Global climate change due to pollution and the effects of pollution on the environment have become major environmental issues since the Rio Summit in 1992.

One of the greatest benefits of renewable energy is its potential to provide clean sources of electricity even to remote populations. Although many people around the world do not have an economical connection to an electrical grid, renewable energy technologies can capture natural sources of (electrical and heat) energy in non-conventional locations and in non-conventional ways.

Rabbi Yitzhak Miller About Electricity By Olivia Alexandria Wilson.

In September 2008, the UK committed itself to cutting carbon emissions by 40 per cent by 2020. In that committal, the British government dedicated its attentions to onshore and offshore wind power in an effort to harness the renewable energy abundantly available; thus reducing our dependency on fossil fuels.

According to the British Wind Energy Association, in order to meet those targets, Britain will have to invest heavily in wind energy with the construction of 12,500 new wind turbines. In theory, clean renewable energy should make electricity prices cheaper, as the bonus of wind energy is that it comes from an infinite source, and therefore will help to stabilise price fluctuations as gas and electricity stocks move on the traded markets.

However, a study from Poyry Energy Consulting has warned that such a significant investment in wind energy will cause havoc for the national grid because of its intermittent nature. Wind turbines cannot harness energy at a consistent rate and variations of output from turbines can change by 25 per cent over a year.

Depending on how much energy is being produced by each wind turbine, electricity prices could fluctuate hugely. At peak times when lots of energy is being produced the turbine would be ultra-effective, making energy virtually free. However, prices could soar to £8,000/MWh at times of low productivity.

Wind is more predictable offshore than onshore, and therefore electricity prices are likely to be more stable with more offshore wind turbines. One of the problems though is that when demand is highest on cold nights, wind turbines are at their most ineffective; whilst conversely, when the warm weather blows stronger winds, demand for electricity is lower.

Energy companies need to have a reliable source of energy that they can depend on in order to provide the best electricity prices for their customers. Wind turbines can certainly help reduce carbon emissions but until they can deliver consistent results, oil, gas and coal will remain the mainstay of power consumption. Whilst that is still the case, home owners will be able to find the cheapest electricity prices by using price comparison sites to search for an energy quote.
