Ocean Energy

Energy consumption in the world is increasing rapidly. Reserves of fossil fuels are diminishing. Turning the use of alternative energy sources is an imperative of the modern era. Not only is it necessary to increase the energy production, but that energy should be clean or environmentally friendly.Energy production should not cause environmental problems such as global warming and air pollution. One of these new renewable energy sources could certainly be the energy of the ocean whose importance will certainly be much higher in the future.

Geothermal Energy

In its essence, geothermal energy is simply heat of the Earth. The heat in the interior of the Earth is due to the formation of planets from dust and gases. In the rocks, process of continuous radioactive decay of elements takes place, which as a result has regeneration of this heat. It is therefore correctly to say that geothermal energy is a renewable source of energy. The heat is from the interior to the surface transmitted by means of water or steam. This component is renewable given the fact that water from the rain penetrates deep into the crevices and there is then heated and circulated back to the surface, where it appears in the form of geysers and hot springs.

Global Warming

In the previous century, the temperature on Earth has increased an average of between 0.6 °C. The hottest recorded year was 2005. If carbon dioxide emissions continue to grow, we can expect an increase in the average temperature of up to 6 °C. Greenhouse gases are collected in the upper atmosphere and have a double impact on the temperature of the Earth's surface. The first effect is a direct rejection of one part of the solar radiation back into space, and the second impact is reflecting a portion of solar radiation that bounced off the Earth's surface back to Earth. This second effect is called the greenhouse effect and this effect is responsible for maintaining a favorable temperature on the surface of the Earth. If there were no greenhouse effect, the average temperature at the Earth's surface would be about -19 ° C, rather than about 15 ° C, which is currently the case. One might say that solution for the problem of global warming is easily trackable: reducing the use of fossil fuels and minimizing deforestation, thereby reducing the concentration of greenhouse gases in the atmosphere. However, in practice this is not feasible due to the inadequate development of alternative energy sources.

Bioenergy

The term bioenergy refers to the energy produced using solid, liquid and gaseous biomass products. Hence, one might reffers to biomass as a renewable energy source, based on number of products of plant and animal origin. Biomass is the biodegradable fraction of products, waste / by-products and residues from agriculture (including substances of animal and plant origin), wood industry, as well as the biodegradable fraction of industrial and municipal waste.It can be directly converted to energy by combustion and thus producing steam for heating in industry and households and gaining energy in smaller thermal power plants. Alcohol fermentation is so far the most advanced chemical conversion of biomass. Biogas is the result of fermentation without presence of oxygen consists of methane and carbon and can be used as fuel, and other modern procedures of energy biomass include pyrolysis, gasification and getting hydrogen.

Water Energy

Water energy (hydropower) is the most important renewable energy source. Water as an energy source is considered to be renewable because of the water cycle in nature. Radiation of the sun causes the evaporation of water from the oceans and rivers and its transformation into water vapor. When water vapor reaches the colder air in the atmosphere, it condenses and creates clouds, thus creating rain or snow and renewing the water in the oceans and rivers. Gravity moves the water from a high pitch to low. The power of flowing water can be very large.
