According to the DOE [link widoczny dla zalogowanych], the power outages and interruptions cost the economy $150 billion annually, much more today than, say, 20 years ago, when digital equipment and appliances had not really proliferated.
Transmission investments by publicly-traded utilities have shown an increase recently, going up to a high of $7.8 billion (up from a measly $2 billion in 1997), but that still doesnt put the grid in a better position. So the question then, is what will? How can this aging unreliable power grid be improved
and scaled for efficient operation into the 21st century? Large-scale overhauling is clearly necessary; and thankfully, that seems to be a very real possibility in the immediate future.
How the Country Plans to Address the Power Crisis
Recently, energy reforms have been identifieded as critical to the economic future of the country and speciffic and time-bound targets for the expansion of clean energy in the US have been set. In the process of overhauling the currently outdated power grid, there is an aim to increase the investment in green energy resources like renewable energy. The target is to double the production of electricity from renewable sources in three years and lay thousands of miles of power lines to carry clean energy to different parts of the nation.
Some Suggestions to Fix the Electricity Grid in the US
In his article in Wired Magazine [link widoczny dla zalogowanych], titled, Power to the People: 7 Ways to Fix the Grid, Now, Brendan I. Koerner offers some interesting suggestions to address the problem of the failing electricity grid in the US:
*Establish local-scale solar power generation near end users. Those implementing this can expect to receive a reimbursement of up to 30% of the cost of the solar energy system.
*Treat electricity like a commodity - something for which demand can be gauged and prices set in advance.
*Pay big users to cut consumption when the need arises.
*The resource allocation towards renewable energy has an impressive $2 billion in grants for battery development. This can be used to develop infrastructure that allows solar and wind energy to be banked when abundant and released later when needed. This way, consumers have access to a
ording to the United States Energy Department, the demand for electricity in the US is growing at the rate of about 1% a year, with that pace likely to increase over the next few years. Other estimates put the increase at 6% or more per year, thanks to the population growth rate and the burgeoning numbers of electric/electronic devices now considered essential to peoples lifestyles. According to the Department of Energy (DOE) 40% of all energy used in the US (oil, gas, wind, solar) is converted into electricity.
Soaring fuel prices at coal and natural gas-red power plants are pushing electricity prices sharply higher. To make matters worse, the DOE estimates that distribution transformers which are 30 years old or more, waste disproportionately high kWhs annually. It is this grid that is expected to transmit the additional gigawatts necessary, and link up with wind and solar power harvested from far-flung areas of the country.
Power outages are now increasingly common in the US. They still tend to be rather brief and specificc in terms of geographic scope but not for long. One of the key reasons for the power outages, beside the aging, outdated power grid [link widoczny dla zalogowanych], is distribution investment. The deregulation wave saw the construction
of many power plants, but a sharp drop in grid investments, with the inevitable overloaded lines and reliability issues cropping up.
Distribution investment as a percentage of revenue has actually been decreasing from 5.7% in the 1980s and early 1990s to 3.5% in the last decade. As a result, the number of blackouts in the U.S. impacting more than 10,000 customers steadily increased over the past 20 years, reaching a peak in
2004 at close to 100 events.
