Europe Energy Powered Via Solar

At the heart of the push to reduce global warming is the search for the most efficient source of alternative energy. Among the debates for alternative sources of energy are photovoltaic solar panels, wind energy, more efficient nuclear power and hydropower, along with a variety of other developmental technologies. One less discussed method of power is concentrated solar power and it is through the use of this method of alternative power that some believe the entirety of Europe could be powered.

Before alternative power theory for Europe can be discussed, one must understand the functionality of concentrated solar power (CPS). CPS systems are commercially used, non-polluting and highly effective, but in general are a less popular form of solar power that consists of using sunlight and mirrors. Large mirrors are used to gather a large amount of sunlight and project it on a small, more concentrated area. The concentrated sunlight is then converted to heat, which in turns powers a heat engine/steam turbine that is connected to an electrical power generator. Currently, it costs about 12 to 18 cents per kilowatt-hour to produce energy using CPS, which is less than photovoltaic solar panels and comparable to the cost using natural gas. To put the figures into a more accessible figure, the price to create energy using CPS is less than the current energy equivalent cost of oil.

According to a study conducted by the German government, by the year 2050, it may be possible for all of Europe, including the United Kingdom and Ireland to be powered by CPS. In addition, the same study reveals that Europe would also be able to reduce its electricity emissions by 79% and it would also be possible to eliminate dependence on nuclear power. These advancements would be invaluable in the fight against global warming. However, with this many environmental benefits in a relatively short amount of time leave many wondering if the plan is actually realistic, or simply too good to be true. The plan outlined in the German study is in fact viable, as long as all European countries would be able to participate.

The plan to harvest enough energy to power all of Europe would require the participation of countries throughout Europe, the Middle East and Northern Africa. The key to the plan lies in the abundance of potential energy in the deserts of these areas. According to the study, it is believed that the equivalent of 1.5 million barrels of oil is available each year in every square kilometer of the desert. With this figure in mind, it is argued the use of concentrated solar power in the entirety of the desert would meet the energy needs of the entire world. While the realization goal may be very far along, the implementation of CPS in a fraction of the desert can produce huge energy windfalls. According to the German proposal, as more CPS plants are produced, less energy efficient plants can be phased out, which would also play a major role in reducing energy related pollution.

On paper, the plan to power the entirety of Europe with solar power seems easy; harvest abundant energy in the desert with concentrated solar power, while simultaneously eliminating outdated power sources. In reality, the corporation of all of Europe's nations, along with the Middle East and Africa is easier said than done. Though it will be undeniably difficult, this dream for an alternatively powered continent could come to fruition. If countries can overcome differences, the goal of an entire world powered by efficient, environmentally friendly energy can be realized.
