The sun is a very valuable source to the world today. We use it for heat, plants use it to grow, and energy such as solar power. Solar power is the conversion of sunlight into electricity. Solar power is the next alternative to all other sources of energy out there. Fossil fuels such as oil and gas are non-renewable, which means they are limited.
Chapter 1 Introduction 1.1 Renewable Energy Resources Self regenerative resources found in nature are called renewable. Energy that is resulting from natural process that is replenished constantly, Resources of renewable energy are sunlight, wind, tides and geothermal heat. Renewable energy exists continuously and abundant in the environment, ready to be harnessed, clean alternative to fossil fuels. Renewable energy put conventional energy in key four areas: Hot water/space heating, electricity production and transportation and off-grid energy services. The major renewable energy resources are the following.
These sources are unlimited, namely wind, sun, natural underground heat, waves and tides. Current conventional energy technologies such as coal, oil and gas, are known as fossil fuels. There are several inefficiencies associated with the usage of fossil fuels. The following methods referred to in this report generate electricity by usage of renewable sources only. 2.1.
Cogeneration is often called combined heat and power (CHP), since most cogeneration systems are used to supply electricity and useful heat. However, the heat energy from electricity production can also be used for cooling and other non-heating purposes, so the term cogeneration is more inclusive. Cogeneration is a form of local or distributed generation as heat and power production take place at or near the point of consumption. For the same output of useful energy, cogeneration uses far less fuel than does traditional separate heat and power production, which means lower greenhouse gas (GHG) emissions as fossil fuel use is
GENERAL OVERVIEW Renewable energy is any energy which has been obtained from a source that is inexhaustible and which is naturally occurring such as solar energy and wind energy. There are many different types of renewable energy with each harnessing a natural source, not all types are equal in their power producing capabilities and each type must be assessed in order to decide which is best suited for South Africa. South Africa has many hot and windy areas, it also has many rivers and dams which can be harnessed to produce energy, South Africa is not a rich country therefore the type of renewable energy must be cost effective and must make sense for the future. The next section will consider renewable energy in a South African
Renewable energies are basically a gift to humans from the nature since their use doesn’t imply energy that derives from fossil fuels. With the development of the renewable technology people have the opportunity to turn these natural energy sources in electricity, heating, cooling and fuels. IEA (2015) reported that ‘Renewable energy will represent the largest single source of electricity growth over the next five years, driven by falling costs and aggressive expansion in emerging economies’. The expectations of Renewable energy sources are that they can affordably mitigate climate change and promote energy security if governments are willing to minimize the policies uncertainties that are barriers in the greater development (IEA, 2015). Environmental protection is one of the top priorities due to the concerns regarding the global weather and air pollution warming.
BENEFITS (ADVANTAGES): Renewable source of electricity. Hydropower plants can produce electricity at a constant rate from water without the water getting consumed. This could be a great infinite source of electricity when the extraction of petroleum reaches an end. Significant source of energy. Hydropower plants in 2009 were providing almost 16.5% of the global electricity production which is equal to 3 329 TWh.
The real solution of this problem can only be done by replacing all these above mentioned non-renewable resources with alternate renewable sources. Solar and wind are considered major example of this but they are not as reliable as coal or gas. So, what should do to overcome this energy crisis. To use all of our available resources in an intelligent way. A fraction of energy should be produced by no-renewable resources and the remaining amount should be fulfilled by that of renewable.
Also fossil fuels are reducing very quickly, so there are critical essential for the world to change to renewable sources of energy which can be recycled again and again. The renewable energy resources are those resources which are free of pollution and free of cost and can be used again and again. The renewable energy resources are the natural energy resources namely sunlight, wind energy, tidal energy, small hydro power, rain, geothermal, and biomass energy are included in distributed energy resources (DERs) .Due to the advantage of the non-polluting, the renewable energy resources are used as a
There are many sources of energy; the most commonly used ones are called fossil fuels. They are made up of coal, oil, and natural gas. They are often called nonrenewable, meaning that when they are depleted, there will be no more in our
