Energy is the key to the success of any time of technology there is in the world today. There are various types of energy depending on their sources. However for the sake of taking care of the environment then it is best to use the renewable energy rather than using the conventional fossil fuels in four distinct areas including electricity generation, hot water and room heating, motor fuels, and rural energy services.
Renewable energy is energy form natural resources. These natural resource are: ocean waves, sunlight, wind, rain, ocean tides, and geothermal heat.
According to research, renewable energy contributes nineteen percent to the world’s energy consumption and twenty two percent to the world’s electricity generation. Both, modern renewables, such as hydro, wind, solar and biofuels together with traditional biomass, are the largest contributors to the world’s energy supply. Worldwide, investments in renewable technologies sums to more than US $200 billion.
The leading countries in renewable energy investments are china and the United States of America. This two countries have heavily invested in hydro energy, biofuels energy, wind energy, and solar energy. However other countries including African countries are coming up in using the renewable sources of energy especially in hydroelectric power generation and geothermal power generation. The swift utilization of renewable energy is causing important energy security, climate change mitigation and economic benefits. Most of them requires some research and then the individual or small group of individuals can easily set up their own. There are loads of renewables info especially in the internet.
Renewable energy is the best form of energy especially for the rural, remote and developing countries. This is because it is cheap and requires lesser knowledge to run it. For example any homestead even in the most remote areas that no one would ever think of having electricity, would acquire a solar panel and use it to get electricity to light the place up.
This is harnessed by using the airflows run wind turbines. There are modern utility-scale wind turbines with an average range 1.5 MW. This technology is used in areas like offshores, and high altitude areas where the winds are strongest.
This is energy that is harnessed from the water. This is the oldest form of modern energy. Mainly it is used in the production of the hydroelectricity. The hydroelectricity is electricity that is obtained from turbines that are turned by high velocity flowing water from dams or water reservoirs.
This is obtained from the ocean surface waves and tidal power. However this are not used commercially due to their complexity and inefficiency.
Solar energy is mainly harnessed by the use of Solar panel. Solar panel can either be the photovoltaic module, a solar hot water panel or to a set of solar photovoltaic modules that are electrically linked and attached on a supporting structure.
This is a form thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. Earth’s geothermal energy originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). The earth’s geothermal energy heats up the water in the earth to steam, then the steam is harnessed and used to turn turbines that generates electricity.
