Solar Energy Pros and ConsToday’s world needs more efficient way of creating and spending energy. The planet is becoming more and more populated and new resources must be promoted in order to ensure that the population is provided with energy and the planet does not have to suffer any consequences. Specialists are carrying research in many areas that are seen as a potential new source of sustainable energy and one of them is the solar energy.
Solar energy is one of the best researched and known types of sustainable energy, it is estimated that individuals have been relying and researching this type of energy even since ancient times. Solar radiation accounts nowadays for most of the available sources of renewable energy. Together with wind and wave power as well as hydroelectricity and biomass, solar energy is one of the most researched and promising types of energy. Yet, only a very small fraction of the available solar energy is used.
The solar energy is currently used to heat water, in most parts of the world. There are several hot water systems that use sunlight to heat water and this is usually typical for low geographical latitude. Specialists have shown that most of the heating systems that are nowadays available can heat water up to 60 degrees C and that these systems are able to provide up to 70% of the domestic use of hot water. Some popular types of solar water heaters are the evacuated tube collectors, the glazed flat plate collectors and unglazed plastic collectors.
One of the biggest downsides of solar energy is that the systems are usually expensive. Although the sun is a valuable source of energy, we all know that it does not shine as much and as powerful in every corner of the world. Thus, it also implies some significant limitations.
