Renewable sources of energy like solar energy are so much in demand these days since other non-renewable sources are depleting up. However, opponents of solar energy had always maintained that it is not a perfect resource since this energy cannot be harnessed at night or during cloudy or stormy days.
But now, a new first large scale solar power plant is being constructed in Nevada which claims to produce and store energy for 24 hours a day and 7 days a week. This plant has been supplied with a loan guarantee of $737 million dollars by the Obama administration. Usually solar power plants absorb heat energy from the sun and use this energy to boil water and turn it into steam. This steam then runs the turbines and generates electricity. But this new solar reserve plant stores heat energy in molten salt which is circulated through the boiler.
In other words, the solar plant will be able to generate electricity even during the night when this advance technology is deployed.
The electricity generation capacity of this solar plant is 110 MW. It basically works when 17,500 heliostats concentrate the solar light on to a collector which is located at the top of a tower of a height of 640-feet and operates at a phenomenal temperature of up to 1050 degrees Fahrenheit.
It is hoped that this latest large scale power plant will prove beneficial as well as economic for the world of renewable energy.
