Natural gas sources have been in use for a number of decades, but it is through the progression of compression techniques that it is becoming a more viable alternative energy source. In particular, it is being used in cars to reduce carbon emissions.

Demand for this energy source has been increasing. In , the lower 48 states of the United States reached record levels of demand and consumption.

Despite this, natural gas does come with some issues. The potential for contamination is larger than with other alternative fuel sources and natural gas still emits greenhouse gases, even if the amount is lower than with fossil fuels. In contrast to biomass energy sources, biofuels make use of animal and plant life to create energy. In essence they are fuels that can be obtained from some form of organic matter.

They are renewable in cases where plants are used , as these can be regrown on a yearly basis.

Biofuels are increasingly being adopted, particularly in the United States. They accounted for approximately seven percent of transport fuel consumption as of Water again proves itself to be a valuable contributor to alternative energy fuel sources with wave energy converters. These hold an advantage over tidal energy sources because they can be placed in the ocean in various situations and locations. Much like with tidal energy, the benefits come in the lack of waste produced.

It is also more reliable than many other forms of alternative energy and has enormous potential when used properly.

Again, the cost of such systems is a major contributing factor to slow uptake. Hydroelectric methods actually are some of the earliest means of creating energy, though their use began to decline with the rise of fossil fuels. Despite this, they still account for approximately seven percent of the energy produced in the United States. Hydroelectric energy carries with it a number of benefits. Better yet, it also offers a number of secondary benefits that are not immediately apparent.

The dams used in generating hydroelectric power also contribute to flood control and irrigation techniques. Nuclear power is amongst the most abundant forms of alternative energy.

It creates a number of direct benefits in terms of emissions and efficiency, while also boosting the economy by creating jobs in plant creation and operation. Thirteen countries relied on nuclear power to produce at least a quarter of their electricity as of and there are currently plants in operation throughout the world.

The drawback is that when something goes wrong with a nuclear power plant the potential for catastrophe exists.

The situations in Chernobyl and Fukushima are examples of this. When most people think of alternative energy sources they tend to use solar power as an example. The technology has evolved massively over the years and is now used for large-scale energy production and power generation for single homes.

A number of countries have introduced initiatives to promote the growth of solar power. This energy source is completely renewable and the costs of installation are outweighed by the money saved in energy bills from traditional suppliers. Nevertheless, solar cells are prone to deterioration over large periods of time and are not as effective in unideal weather conditions.

As the issues that result from the use of traditional fossil fuels become more prominent, alternative fuel sources like the ones mentioned here are likely to gain further importance. Their benefits alleviate many of the problems caused by fossil fuel use, particularly when it comes to emissions. However, the advancement of some of these technologies has been slowed down due to the amount of investment needed to make them viable. Through combining them all we may be able to positively affect issues like climate change, pollution and many others.

Please do contribute to the discussion below and let us know your thoughts on alternative energy sources in the comments section or by sharing this article on social media. Skip to content The potential issues surrounding the use of fossil fuels, particularly in terms of climate change, were considered earlier than you may think.

Bioethanol is an alcohol made by fermentation , mostly from carbohydrates produced in sugar or starch crops such as corn , sugarcane or switchgrass. Biodiesel is made from vegetable oils and animal fats.

Biodiesel is produced from oils or fats using transesterification and is the most common biofuel in Europe. Biogas is methane produced by the process of anaerobic digestion of organic material by anaerobes. Biogas typically refers to a mixture of gases produced by the breakdown of organic matter in the absence of oxygen. Biogas is produced by anaerobic digestion with anaerobic bacteria or fermentation of biodegradable materials such as manure , sewage , municipal waste , green waste , plant material , and crops.

Natural fibres are a class of hair-like materials that are continuous filaments or are in discrete elongated pieces, similar to pieces of thread. They can be used as a component of composite materials. They can also be matted into sheets to make products such as paper or felt. Fibres are of two types: Renewable resources are endangered by non-regulated industrial developments and growth. This is a matter of sustainability in the natural environment. National Geographic has described ocean over fishing as "simply the taking of wildlife from the sea at rates too high for fished species to replace themselves.

Tuna meat is driving overfishing as to endanger some species like the bluefin tuna. The European Community and other organisations are trying to regulate fishery as to protect species and to prevent their extinctions. The decline of penguin population is caused in part by overfishing, caused by human competition over the same renewable resources [62]. Besides their role as a resource for fuel and building material, trees protect the environment by absorbing carbon dioxide and by creating oxygen.

Deforestation causes carbon dioxide to linger in the atmosphere. As carbon dioxide accrues, it produces a layer in the atmosphere that traps radiation from the sun.


The radiation converts to heat which causes global warming , which is better known as the greenhouse effect. Deforestation also affects the water cycle.

It reduces the content of water in the soil and groundwater as well as atmospheric moisture. Rain forests house many species and organisms providing people with food and other commodities.

In this way biofuels may well be unsustainable if their production contributes to deforestation. Some renewable resources, species and organisms are facing a very high risk of extinction caused by growing human population and over-consumption. Other conservation methods include restricting land development or creating preserves.

Besides fears about an upcoming global shortage of fossil fuels , local shortages due to boycotts, war and blockades or just transportation problems in remote regions have contributed to different methods of replacing or substituting fossil resources based on renewables.
