It is well known that our standards of living depend on energy. These last years, modern technologies have developed to such extent that everything we use nowadays needs energy. In one hand, It is true that these energies make our lives much easier, but in another hand, these energies have negatives effects on our planet included the living beings. According to the European Commission, the augmentation of Carbon dioxide (CO2) that is released by human activities (industries) as well as the using of fossil fuel, causes the global warming. The high demand of fossil fuel are harmful for humans and animals' health. Fortunately, in the recent years, scientists have created different technological advancements that are beneficial to our world's natural resources and are protective to our planet. Today many people believe on "going green"," which according to research keeps the earth healthy. These technologies called the Green Energy are an important aspect in the developed countries. According to Joshua D. Kneifel, the public's growing concern for the environment and progressively strict regulation of emission in the electric power industry has driven policies to increase the amount of renewable energy. Although, pollution caused by the different forms of humans' activities is a serious issue in many countries, it is time to face the problems by using green energy such as solar energy, wind energy, hydroelectricity, and wave power. In the following show-case, I will explain each of the forms of the green energy.
The first form of green energy is the Solar Energy. The solar energy is the light from the sun converted into heat energy or electricity. It is the oldest form of green energy. Historically, Solar Energy has always provided practically all of humanity's energy. For example, early Chinese architecture incorporated solar design to provide heat in interior spaces. Also, Romans had created the clear glasses windows to set-up the heat.
