Solar energy: Clean source of electricity for the planet

(Continued)

After the Fukushima nuclear disaster in March 2011, Germany shut down all 17 of their nuclear plants for safety reasons. Following a review, nine plants were restarted, but all will be phased out by 2022. The government and German people are uncomfortable with nuclear power, its safety issues and the need for long-term waste disposal. They lived through the Chernobyl disaster and saw what happened to Japan after the Fukushima Daiichi meltdown. 

With financial incentives, feed-in tariffs and subsidies (like the United States still gives the fossil-fuel industry), PV and wind power have become a major, and growing, source of their electrical supply. 

They recognize that burning fossil fuels and putting carbon dioxide, a pollutant, into the atmosphere is a cost that is being socialized in that all people everywhere are paying the price of this pollution and not the power-generating companies. The cost of this air pollution is not fully reflected in the price of electricity consumed. 

Two highlights have occurred recently that tell a powerful story. In August 2011, sufficient wind-powered electricity was being generated that Germany had too much power going into the grid. They had to shut or power down fossil-fuel-burning plants to bring supply and demand into balance. Then, in May 2012, Germany’s PV-generated power temporarily met more than 50 percent of its electrical needs. 

They are able to integrate renewable energy into their requirements and still be the industrial powerhouse of Europe and the second-largest exporting nation on the globe, behind China.

The cost of PV has been dropping dramatically over the past three decades. The Department of Energy graph through 2009 illustrates this. The last three years have seen additional price drops, making PV very competitive with other generating sources in many markets. 

What are we waiting for?
