Examples of Renewable Energy Sources

We have all become more aware of the environment in recent years and the impact that our lives are having on it. This includes the problem of energy resources. We know we are running out of certain energy sources, such as oil, and in the future renewable sources are likely to become a priority, a trend that has begun but still has a long way to go. So what are some of the renewable energy sources that we are beginning to utilise more extensively?

Solar Power

The sun produces the energy for trees and plants to grow and we humans can also take advantage of the sun to produce the energy we need. This is done by using solar panels, something that, while not utilised by the majority, are becoming more common on homes and other buildings. In an individual home solar panels can be used to heat the home and the water used within it. Solar energy can also be harnessed and stored for use elsewhere.

Wind Power

Wind power is a completely clean energy source as wind turbines don’t produce any emissions at all. It does, though, require wine turbines to stand in open countryside, often in coastal areas to benefit from where the highest wind speeds are. Some are against this as they consider them to be a blot on the landscape they are situated in. Currently, wind power is the fastest growing renewable energy source and it could be key in the future.

Biomass

Biomass can be turned into an energy source by it being burnt. This is currently done by burning products such as plastic, insulation and fabric. This isn’t particularly clean energy and replacing this with burning biomass products will lead to fewer harmful emissions being released into the atmosphere. Biomass products that could be used to replace things like plastic include trees, dead plants and food wastage, all of which are natural products.

Water

Referred to as hydropower, water can be an extremely effective source of power. This can be achieved by utilising waves or falling water in the form waterfalls or building purpose built dams. The most common way in which water is used for energy is through hydroelectric power, which is the process of turning this energy into electricity. This is the most extensively used form of renewable energy used worldwide. The cost of hydroelectric power is relatively low due to the natural gravitational force of waterfalls or flowing water often being utilised. Even where investment is required - for example because a dam has to be built - once completed it is cost effective.

These are just some of the renewable energy sources that could be used more extensively in the future. These are the most common, but there are others too, and there are sure to be more developments over time. The efficiency of renewable sources of energy is likely to improve. With the human population continually growing and technology advancing we are going to require even more energy in the future. The need for clean and renewable forms of energy is a pressing concern and something that will become more necessary as time goes by.

Due to developments in the energy sector it is important that energy providers keep up with Energy Law.
