New National Grid to Optimize Use and Transport of Alternative Energy Sources
In February the National Clean Energy Project conference convened, where a veritable army of policymakers and policy experts caucused over the need for a modernized electric grid in the United States. This new latticework of power lines buttresses the Obama administration’s efforts to promote alternative energy sources, which will need an effective transport system, comprised of a high-voltage mainline and state-of-the-art grid technology, to actually be effective. For example, the American Southwest may have solar plants galore, but since sunlight is a transient alternative energy sources, the energy captured may never reach, say, Virginia. Additionally, the electric grid would also need “two-way flows” to effectively disperse surplus alternative energy sources from one structure to another. This is in addition to the stimulus package $4.4 billion for “modernization of the electric grid” and $8 billion for transmission improvements, with entirely separate measures for climate legislation to cap carbon-dioxide emissions.
Secretary of Energy Steven Chu reiterated transient energy conundrum with wind and solar energy: how do you store alternative energy sources that are not constant? In the U.S. wind and solar energy production only comprise 0.8% and 0.02%, respectively. However, aggregate estimates state that solar and wind could have potential outputs of up to 69% and up to 20%, respectively. At such quantities, storage becomes a problem. In times of no sunlight and no wind, Chu suggested the U.S. expand its pump-hydro storage capacity while developing compressed-air storage. Transporting the alternative energy sources will then present the prospect of perpetual resistance from local governments about having to build through their areas. Senator Reid’s solution was to introduce a bill expanding presidential powers to designate “renewable energy zones,” where the federal government could overrule local governments.
