Presently, our energy process depends on foreign oil that is subject to price volatility, increasingly unreliable, as well as produces twenty five % of the world's co2 emissions. Why will we want to continue using a system this way when we could use a sustainable energy system where we'd have carbon neutrality, diverse supply options, and efficiency? Some other benefits include a sustainable impact on energy and also the development of high value tasks. A transformation like this would demand new approaches in the enhancement of a carbon neutral energy system.
Currently, the electricity system of ours is in excess of 70 % dependent on fossil fuels. Based on EIA Electricity Monthly (March 2009), the principal energy sources utilized to generate electricity are coal (48.5 %), natural gas (21.3 %), nuclear (19.7 %), hydroelectric conventional (6.1 %), various other sustainable sources (3.3 %), and oil (1.1 %).
Right now, solar energy symbolizes probably the most significant resource. It has a 206,000 gigawatt (GW) opportunity infinity coil for electricity (Visit Web Page) photovoltaic and a 11,000 GW possibility of concentrating solar energy. Using wind, you are looking at 8,000 GW potential (on shore) and 2,200 GW (off shore). Geothermal follows at 39 GW from convention resources and 520 GW from enhanced geothermal systems as well as 4 GW from coproduced sources. As you can see from these numbers, the US renewable energy resources are much more than capable for meeting a large part of our electricity system needs.
Nevertheless, renewable power is actually contributing more and more to the energy grid. In 2008, renewable energy comprised 45 % of new capacity versus only ten % in 2005 based on the National Renewable Energy Laboratory.
The states have taken the lead in using renewable energy for electrical energy production. twenty nine states have adopted RPS (Renewable Portfolio Standards). A RPS is a state policy which requires electricity providers to reach a minimum percentage of their electric power from renewable energy resources. Now, wind is the main electricity resource. Nevertheless, to insure that several of the projects incorporate things such as solar energy, they have established minimum solar energy requirements. A Federal RPS policy is also being considered.
Why is a RPS so important? The american states collectively provider for over 50 % of the electricity sales in the US! The Global Environment Fund estimates that the current status RPS would eventually cause the installation of more than 75,000 MW of renewable strength.
The ability for using inexhaustible energy resources prevails right now and can produce a significant component of the vitality grid come 2050. 2050 will be the timeframe that the US need to have an ideal portfolio of coal, nuclear, and unlimited energy to meet the electricity needs of the country. It is not a possibly or situation any longer. All sources of electricity will have to be used to satisfy our ever growing need. As shown by the states' RPS, in case you provide financial rewards (such as federal tax credits, the ability to see excess power, etc.), they will come. The problem since must be asked is: what is going to be the task of unlimited power be down the road?
