Different Sources of Alternative Energy (part 3)


  1. Biofuels

Contrasting to biomass energy sources, biofuels make use of plant and animal life to create energy. They are fuels which can be obtained from some form of organic matter. They are renewable if plants are used because these can be regrown on a yearly basis. However, they require dedicated machinery for extraction, contributing to increased emissions even if biofuels themselves don’t. Biofuels are being adopted more and more, particularly in the United States.

  1. Wave Energy 

Once again, water proves itself to be a valuable contributor to alternative energy sources with wave energy converters. They hold an advantage over tidal energy sources as they can be placed in the ocean in different situations and locations. It has enormous potential when used properly and is more reliable than many other forms of alternative energy. However, the cost of these systems is a major factor to slow uptake.

  1. Hydroelectric Energy

Hydroelectric methods are among the earliest means of creating energy, although their use has declined with the rise of fossil fuels. However, they still account for about seven percent of the energy produced in the United States.

Hydroelectric energy brings a number of benefits. It is also a renewable energy source that doesn’t create pollution. Moreover, it offers some secondary benefits which are not immediately apparent. Generating hydroelectric power also uses the dams that contribute to flood control and irrigation techniques.

  1. Solar Power

Ssolar power is an typical example of alternative energy sources. After having been evolved massively over the years, it is now used for large-scale power generation and energy production for single homes. Many countries have introduced initiatives to promote solar power. Solar power source is totally renewable and the costs of installation are outweighed by the money that is saved in bills from traditional suppliers.

However, solar cells are prone to deterioration over long periods of time and are not so effective in unideal weather conditions.
