Green Energy
Many researchers are trying to find new renewable energy sources to help diminish carbon emissions, which cause global warming. Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many countries and is harmful to humans’ and animals’ health, the environment and also increases pollution (Veziroglu 2007). Now, it is the time to face these problems by using clean energy such as solar, wind and water. Wagner & Mathur (2011) state that hydropower is the most efficient renewable energy, while Veziroglu (2007) claims that hydrogen is the key to the solution in the 21st century. Therefore, this essay will focus on energy sources water and hydrogen. The first part will analyse how to use water to produce a large amount of power in several ways. The second will discuss the effect of hydro energy. The third point will explain where hydrogen comes from and how to use it. The last section will describe the reason why many researchers and industrialists are interested in using hydrogen power. It is argued that using hydro power and hydrogen energy in many countries can decrease CO2 emissions that are the main cause of climate change and create an amount of clean energy, although these sources of energy have some negative impact and requires high investment costs.

Hydro is a large natural resource that can be used to generate power in different ways. Hydro means water which is a significant power source to generate electricity. Destouni & Frank (2010) state that hydro-electric is a large resource, and it is more stable and reliable than other resources when they are compared. Additionally, the electric can be produced from water by using generator in many ways.

    In recent decades, there has been an increased need to produce sufficient renewable energy to support global population growth. In response, it has become crucial to find socially responsible sustainable energy resources that offer energy security, reduce greenhouse gas (GHG) emissions, and do not compromise biodiversity or sustainability of existing resources. Despite efforts to reduce the amount of waste produced, a continually growing population limits the space available in landfills. Municipal and industrial waste biomass is often rich in organic matter, allowing for the creation and use of biofuels as an energy source. This organic matter can be used to synthesize ethanol, methanol, and biodiesel through the conversion of inorganic compounds into energy-producing organic carbon compounds. Moreover, unlike fossil fuels, which take millions of years to form, these organic carbon compounds are formed relatively quickly. Biofuel production from waste is beneficial as it allows for better management of landfill sites, and energy production from materials which typically cannot be recycled or composted. Most importantly, it allows for the reduction of significant amounts of methane produced from landfill gas emissions.…

    Hydroelectric energy is a renewable source. It can come from fast moving water or a dam can be created to drop water and increase its speed. Dams raise the height of water on the upstream side of the dam, giving it more gravitational potential energy. The water then drops through pipes in the dam transferring the potential energy to kinetic energy. The water hits turbines which turn generators changing the kinetic energy into electricity.…

    Many nations count on coal, oil and natural gas to supply most of their energy needs, but reliance on fossil fuels presents a big problem. Fossil fuels are a finite resource. Eventually, the world will run out of fossil fuels, or it will become too expensive to retrieve those that remain. Fossil fuels also cause air, water and soil pollution, and produce greenhouse gases that contribute to global warming. However, we are now realizing the problems that are created by using fossil fuels to generate energy. As we have realized that our energy sources are depleting, or getting very harmful for the environment. These problems are so great that they will force humans to find an alternative source of energy in order to avoid the inevitable disasters that lie ahead.Renewable energy resources, such as wind, solar and hydropower, offer clean alternatives to fossil fuels. They produce little or no pollution or greenhouse gases, and they will never run out.The benefits of ditching fossil fuels for hydrogen are many, of course. Burning fossil fuels like coal, natural gas and oil to heat and cool our buildings and run our vehicles takes a heavy toll on the environment, contributing significantly to both local problems such as elevated particulate levels and global ones such as a warming climate. Hydrogen will ultimately be our environmental saviour, replacing the fossil fuels responsible for global warming and various nagging forms of pollution. The only by-product of running a hydrogen-powered fuel cell is oxygen and a trickle of water, neither of which will cause any harm to…

    Hydropower is a renewable source of power used throughout the world. It uses the force of water to generate power sustainably. A big concrete wall is built in a fast flowing river and water builds up behind it all the while the pressure is building up. As the energy level rises to a maximum, the water is released and as the fast moving water passes through turbines which then convert the waters energy into power. It works when water I channeled into water turbines. The force of the moving water, makes the turbine blades move and powers an electrical generator, which converts the power into energy. Hydropower is the most efficient and advanced way of making renewable power and is used in more than 170 countries worldwide. Hydropower is renewable because after the water has made its way through the hydropower station in continues downstream to the sea. At sea level it evaporates because of the heat. It then rises up through the atmosphere and turns into clouds as the air cools. The clouds then rise which causes more condensation, which then results rain. The rain then falls into the rivers again where the cycle begins again.…
