Renewable Energy Efficiency

08 Mar Renewable Energy Efficiency

Renewable energy efficiency

Experts have declared that fossil fuels will not last forever. Having taken millions of years to become the energy dense materials that we use to power our lives today, it has become evident that time is finally running out, and fast. It’s also safe to say these kind of fuels will not be easily replaced either. At the rate we are using them globally we will have to replace them, however, as once they are gone, they are gone. The good news is, there are other great alternatives available. In this blog, we’ve been taking a look at how renewable energy is progressing, and which variable technologies we are already using today.


What are signs of change?

Total investment in renewable energy in 2015 was equivalent to more than double the amount spent on coal and gas power plants, according to the Renewables Global Status Report, so renewable energy is receiving investment. In addition, renewable energy is set to account for one quarter of global electricity by the year 2020. This is a good indication that people are beginning to understand that it isn’t a case of ‘if’ we run out of fossil fuels, but ‘when’?


What renewable energy is already being used?


This is the most widely used form of renewable energy as hydropower can convert 90% of available energy into useable power, making it the most efficient way to generate electricity. Currently 21% of the world’s electricity is powered by hydropower and this energy supplies 30 countries worldwide. The efficiency of this power is unrivalled by any fossil fuels, so it is likely that in the not too distant future, homes all over the world will rely a great deal on hydropower for their energy.



In second place for most used renewable source comes wind energy. This is the fastest growing renewable energy currently, and in an average year it can make up 11.4% of annual energy use in the EU. In the UK specifically, for the first time ever wind energy overtook coal power for the amount of electricity generated, keeping the UK on track to stop reliance on coal power entirely by 2025.



Solar energy comes from the Sun, and the Sun is the most abundant energy source available to us on Earth. The world is constantly blasted with energy from the Sun, receiving 143 times more energy than 1.3 trillion horse power at any given moment. The problem with solar power is that very frustratingly, we only have the technology to harness 0.0001% of this energy. Even so, solar energy has proven useful with contributing towards home energy. A growing number of solar panels are being installed, with the total figure in the UK by expected to reach 10 million by 2020.  


Becoming more energy efficient

 It is clear that renewable energy beginning to attract significant investment globally, and that fossil fuels will eventually be a thing of the past. But although these new renewable energies are working well, they are still very much in development. It is important then that we begin to use the energy we currently have more efficiently, therefore, and complete tasks using as little power as possible. This will ensure current energy reserves last longer, and gives more time for renewable energy to develop into a robust and reliable energy source that can be used at maximum capacity.


In order to do this, there are several things anyone can do in their home to improve overall energy efficiency. Switching off lights that aren’t being used, replacing older light bulbs with energy efficient alternatives, replacing ageing appliances that can take a lot of energy to work with newer models, only charging your phone when necessary and taking shorter showers are all small changes that everyone can make, but when introduced on a wider scale can make a huge difference.


More significant changes that can also be made to ensure your home becomes more energy efficient include keeping heat in the home is a sure way of ensuring you are using as little energy as possible. Escaping heat is extremely wasteful, so sealing windows, getting double glazing and insulating a property are all effective ways of increasing a home’s energy efficiency, as well as reducing the amount of energy required to run it in the first place.


SPMS Wales are experts in insulation. Whatever the property and whatever the situation, we are confident that we can help. If you are looking to the future and want to help by becoming more energy efficient, get in touch today by phone on 01656 818881, or email us at
