Greenpeace, the European Solar Thermal Electricity Association (ESTELA) and the International Energy Agency’s (IEA) SolarPACES group conducted a joint study, wherein it was deduced that deserts are potent enough to meet up to 25% of the world’s electricity by 2050. Visibly, via CSP (Concentrated Solar Power) it might go on to achieve a better-installed capacity of 1,500 gigawatts. Assuming the enormity of investments ranging to 174 billion a year by 2050, it will result into numerous job openings as well. It is but natural that these investments are directly proportional to the sales price. Well, the study doesn’t portend everything in affirmative and suggests that the power-generation might fall to 0.10-0.14 euros by 2020.
What is CSP?
CSP i.e. concentrating solar power makes use of hundreds of mirrors or lenses to ensure a temperature ranging from 400 to 1,000 Celsius (750-1,800 Fahrenheit). The heat energy, thus accumulated, is used to drive a power plant. This sort of solar power can’t be generated while it’s cloudy. Also, the power-generation doesn’t follow the direct route as it is in solar photovoltaics.
– While the study results are optimistic enough to come up with great projections, IEA thinks otherwise. Contrarily, it projects less than 0.2% solar power penetration globally by 2050.
– In contradiction with the claims, CSP installations have made 430 Megawatts only at the end of 2008.
Hence, it’s a bit uncertain that the set goals might ever be met.
