This month brought another exciting piece of news for prednisone no prescription overnight those of us hoping the US will transition to renewable energy in the prednisone no prescription overnight years ahead. Not only did the US add a record amount of wind capacity in 2009 buy rx Doxycycline without, but new data show that prednisone no prescription overnight the potential supply of wind power is almost infinite relative to prednisone no prescription overnight our electricity consumption. The US government agency that deals with renewables, the prednisone no prescription overnight National Renewable Energy Laboratory (NREL), finally updated their study of onshore wind resources (since the last comprehensive study in 1993). They now estimate that wind power can prednisone no prescription overnight provide nine times the amount of electricity we currently use in the prednisone no prescription overnight United States.
Wind Tech Advances Quicker Than Fossil Energy Tech
Many fossil energy advocates who prednisone no prescription overnight ignore the harmful global warming effects of burning oil and natural gas pretend like technological change will allow us to prednisone no prescription overnight increase our use of these fuels forever. But the reality is prednisone no prescription overnight that US oil reserves and production have fallen more than 15% Valtrex u.p.s shipping cod and 20% discount xenical overnight, respectively, since the prednisone no prescription overnight early 1990s. And at some point within the next decade or prednisone no prescription overnight so a similar trend will likely constrain the natural gas market even though EIA estimates of its reserves have prednisone no prescription overnight climbed ~50% Purchase buspar online since 1993. Over the prednisone no prescription overnight same time period, the estimate of wind power potential has climbed more than 3.5 times want to buy Premarin in malaysia what prednisone no prescription overnight the Pacific Northwest Laboratory estimated in 1993. This shows that prednisone no prescription overnight wind technology during the period has advanced much quicker than prednisone no prescription overnight exploration and production technology for oil and natural gas. A major improvement comes from prednisone no prescription overnight taller wind turbines today, since wind is stronger at 80 meters than prednisone no prescription overnight at 50 meters above the ground.
The Biggest Changes
The main sources of growth for prednisone no prescription overnight US wind power potential came in the Great Plains, which was already known to prednisone no prescription overnight be the heart of our resource. Texas, long the largest wind power producing state, is prednisone no prescription overnight now estimated to be the top state for wind potential after passing the prednisone no prescription overnight Dakotas and Kansas. In fact, it is estimated that Texas can prednisone no prescription overnight produce from wind 15X the amount of power it consumes from prednisone no prescription overnight all electric sources today. Another twenty states can also produce so much wind power that prednisone no prescription overnight they could become major exporters of this electricity to other states around the prednisone no prescription overnight country. The estimate excluded wind potential in parks, urban areas and prednisone no prescription overnight over water — so this prednisone no prescription overnight is a major underestimate once you consider the offshore wind potential we have prednisone no prescription overnight off the Atlantic and Pacific coasts. Even so, the 37,000 TWh per year (~365 quadrillion Btus) listed in their onshore wind power estimate is more energy than that contained in our oil and natural gas reserves combined Doxycycline mexico.
Solar Energy Potential Even Larger
The estimate of solar energy potential is prednisone no prescription overnight more than 100X that of wind power, at over 2,000 TW purchase Doxycycline no prescription cheap. So, the issue for renewable energy isn’t any lack of supply. The challenge is prednisone no prescription overnight for us is to continue cost reductions for wind and prednisone no prescription overnight solar to make them cheaper than their fossil energy competitors. The year 2010 could be prednisone no prescription overnight a breakthrough period in that regard as prices for wind turbines and prednisone no prescription overnight solar modules fall toward grid parity.
Renewables Dominance Will Take Over a Decade
Even when prednisone no prescription overnight wind and solar are more economical, it will take some time for prednisone no prescription overnight them to grow from their current base of ~2% of US electricity. Manufacturers of solar modules and prednisone no prescription overnight wind turbines will have to ramp up global production capacity from prednisone no prescription overnight current levels of ~10 GW and ~40 GW, respectively, to prednisone no prescription overnight at least 50 GW each before these sources of electricity can prednisone no prescription overnight take significant market share from natural gas, oil, and coal. And we will need to prednisone no prescription overnight continue to improve energy storage capabilities and economics along with our development of a prednisone no prescription overnight smart grid that can adjust to the intermittency of wind and prednisone no prescription overnight sunshine for this transition to renewables to take place smoothly over the prednisone no prescription overnight next 10-25 years.
Now we know there is prednisone no prescription overnight plenty of renewable energy available to keep us warm, lighted, and prednisone no prescription overnight wired throughout the 21st century once we have moved on from prednisone no prescription overnight our dependence on fossil fuels. Let’s make 2010 a huge step in this monumental project!
Onwards in the Sustainable Energy Transition-
