In the last ten years, renewable energy sources such as wind power and solar energy have seen incredible growth, diversifying and decentralising energy provision and putting downward pressure on energy prices. But despite the cost-effective nature of these alternative energies, their share in the worldwide energy pool has remained relatively low, at around 16% and 12% respectively.
In 2019, wind power and solar energy were responsible for around 16% of the world’s total electricity generation – more than a quarter of which was in China – and this share is predicted to rise to around 23% and 20% respectively by the end of the decade. In the UK, the share of renewable energy sources in our energy mix has risen from just 1% in 2009 to over 15% in 2019.
Solar energy is one of the most popular and most prominent renewable energy sources, due to its perceived limitless supply, coupled with the growth of the global solar industry in the last decade. The share of solar power in worldwide energy generation has increased from 4.7 gigawatts (GW) to 16.3 GW between 2010 and 2019, with China accounting for around 70% of the growth in solar power generation since 2010.
The cost-effectiveness of solar power is clear to see. It takes just three to four minutes for a rooftop solar panel to generate enough electricity to power a light bulb. The investment threshold for putting a solar panel on your roof is minimal, compared to other forms of renewable energy, and the pay-back time on this investment is extremely fast, usually happening within a year. If you live in a sunny location, the energy generation of your rooftop solar panel will more than pay for itself in just a few years’ time. This is why solar power is such a popular choice amongst homeowners who want to be more independent of the energy company.
But the most appealing feature of solar power is its perceived green credentials. The solar panels on your roof produce no toxins, emit no pollutants, and require no fuel to generate energy. This means that, from an environmental perspective, solar energy is seen as the greenest form of energy generation available today.
Wind power is probably the most famous renewable energy source. After all, where would we be without the pleasant sound of the wind? On the surface, wind power seems like an easy option to go green, as it’s entirely pollution-free and requires no fuel to operate. Furthermore, the wind can be harnessed almost anywhere, regardless of location or climate, which makes it a truly versatile and renewable energy source.
But just like solar energy, the popularity of wind power has increased largely due to its low price point. The cost of generating electricity from a wind turbine is around a quarter of the cost of generating electricity from a conventional source. Furthermore, there’s a global wind farm generation capacity of around 6.8 GW, which accounts for around 10% of total worldwide energy generation – around the same percentage as coal. This makes wind power an attractive option for businesses and homeowners looking to save money while also contributing to a more eco-friendly energy mix.
Reasons To Combine The Two
Combining the energy sources on your roof can significantly increase your property’s efficiency and reduce your electricity bills. By installing a system of solar panels and wind turbines on your roof, you’ll be able to harness the power of the sun and wind to generate electricity that you can use directly on site. Not only will this cut down on your carbon footprint, but it will also make you independent of the electricity company, ensuring that you always have the power on when you need it.
There are a number of benefits to combining solar panels and wind turbines on your roof. First and foremost, you’ll be able to generate as much electricity as you require, whenever you want, depending on the weather and daylight conditions. Second, the energy produced from the panels and turbines will be significantly more affordable than if you were to purchase these items separately. Finally, you’ll be contributing to a more sustainable energy mix, helping to reduce the world’s dependency on fossil fuels.
Choosing a system of solar panels and wind turbines will not be easy. Before purchasing any equipment, it’s essential that you understand how these two forms of renewable energy work together and which one you might prefer. To learn more, contact us today.
