After experiencing the replacement of manual and animal labour by steam engines in the Industrial Revolution, cheap fossil fuels then became the main source of energy. However, faced with the notable increase demand for energy, fossil fuel, as a non-renewable resource becomes scarcer and more expensive nowadays. To solve this problem, the world needs to replace fossil fuels with other sources of energy which are relatively low-cost and more secure. Renewable energy is such a potential energy. This essay will give an outline of three sources of renewable energy to be used in developing nations, which are solar energy, wind power and biomass. First, it will give a definition of fossil fuel and renewable energy, then it will move to analyse …show more content…
Another advantage for developing nations using renewable energy is to help local economic develop, since investments are taking place and facilities are built and maintained, bringing employment a boost. Regions that still require fossil fuel to provide electricity and heating may spend a great deal of money on imported fuels. Therefore, renewable energy shows a big potentiality in future energy supply.
To start with, as Volker (2005) mentioned, solar energy is an inexhaustible supply of energy. Yet there is far less an agreement about this. Franchi (2005) claims that energy from the Sun is terminate since the Sun is measured to remain its life for millions of years. Human now consider solar energy as a renewable energy because it should persist being available for many generations of people. Though it is generally accepted that solar power might have a great potential in the future energy supply, it is important to bear in mind that for some developing countries, this may call for high technology and expenditure which they cannot afford. Great efforts have been made to reduce the cost of solar thermal plants (Middleton, 2003; Seitz, 2002), however, solar cells are still relatively expensive, thus result in the limitation of wider use, especially in the developing world (Seitz, 2002).
Solar energy has already shown its promise
