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.

  1. Biomass Energy

Biomass energy comes in various forms. Burning wood has been used to create heat for thousands of years, but recent advancements have also seen waste.

The generated heat of burning wood can be the same as that of a central heating system. Moreover, the involved costs tend to be lower and the amount of released carbon by this kind of fuel is lower than the amount released by fossil fuels.

However, there are some issues that you need to consider installing these systems in your home, including maintenance and permission from a local authority.

  1. Wind Energy

Wind energy has become more and more popular in recent years. It offers some benefits that are the same as many other alternative fuel sources. For example, it generates no waste and makes use of a renewable source.

Wind energy installs power in about twenty million houses in the United States each year and this number is growing. Nowadays, most states in the US have some form of wind energy set-up that continues to grow.

Unfortunately, this energy generation form also presents some challenges, including wind turbines restricting views and being dangerous to some forms of wildlife.

  1. Geothermal Power

Basically, geothermal power means extracting energy from the ground around us. Nowadays, it is growing more and more popular. The World Bank estimates that about 40 countries can almost meet their power demands using geothermal power.

This power source does little to disrupt the land and has massive potential. However, due to its high costs, there is slower adoption of  geothermal power plants than expected for a fuel source with so much promise.

  1. Natural Gas

Although natural gas sources have been used for some decades, it is through the progression of compression techniques to become a more viable alternative energy source. Particularly, it is being used in cars in order to reduce carbon emissions.

Demand for natural gas has been increasing, however, it comes with some issues, including emitting greenhouse gases.

Different Sources of Alternative Energy (part 1)


The issues that surround the use of fossil fuels, especially in case of climate change, were considered earlier than we think. In 1896, Svante Arrhenius, a Swedish scientist, was the first person stating that the use of fossil fuel could contribute to global warming.

This issue has become a hot topic for the last few decades. Nowadays, there is a general shift towards environmental awareness while the sources of energy are coming under closer scrutiny. Therefore, a number of alternative energy sources have risen and contributed something positive when being compared to fossil fuels. Lower emissions, lower prices, and the reduction of pollution are all advantages which the use of alternative energy can provide.

Here we write down the list of the most prominent alternative energy sources as well as the benefits they offer and potential for increased uptake in the near future.

  1. Hydrogen Gas

Hydrogen is completely clean burning fuel, unlike any other form of natural gas. Hydrogen gas cells emit only warm air and water vapor when in use.

However, it is mostly derived from the use of fossil fuels and natural gas. Therefore, it can be argued that the emissions which are created to extract hydrogen gas counteract the benefits of its use.

Although the process of electrolysis, essential when splitting water into oxygen and hydrogen, makes this less of a problem, electrolysis can still rank below the previous methods for extracting hydrogen, despite the fact that research continues to make it more efficient.

  1. Tidal Energy

Tidal energy uses the water power to generate energy, much like with the hydroelectric method. However, in many cases, its application has more in common with wind turbines.

The potential of this fairly new technology is enormous. A recent report in the UK estimated that tidal energy could meet up to 20% of the current electricity demands of this country.

The use of Tidal Stream Generators is the most popular form of tidal energy generation. These use the ocean’s kinetic energy to power turbines, without producing any waste of fossil fuels.

Global Warming Climate Change Affects Upon the Ozone Layer

Very few people will deny that global warming climate change is one of the most topical issues facing this world today. We have also heard how global warming climate change can affect the ozone layer. Scientists believe that as greenhouse gas emissions continue to heat up the earths atmosphere, it will affect the ozone layers […]
