Renewable energy is clean and efficient. This means that each property owner who uses this form of energy plays their role in protecting the environment.

This efficiency also means that renewable energy users can improve the EPC rating for their property.

Along with other articles that have appeared on the Summit Environmental Blog here we have top questions and answers about the renewable heat sources that are becoming not only more popular but also more affordable for the average man in the street.

To support the renewable energy roll out there is an ever increasing range of grants and retro fit packages that make it worth your while to look at renewable energy sources sooner rather than later. It may be the case that you will need to pay for the new technology initially, but you will be able to get a pay back over seven years.

What are the top five sources of renewable energy?

There are five major renewable energy sources?

  • Solar energy from the sun.
  • Geothermal energy from heat inside the earth.
  • Wind energy.
  • Biomass from plants.
  • Hydropower from flowing water.

Which country is leading in renewable energy?

The leading countries for installed renewable energy in 2020 were China ,the U.S., and Brazil. China was leading in renewable energy installations with a capacity of around 895 gigawatts. The U.S., in second place, had a capacity of around 292 gigawatts.

What is the best natural source of renewable energy?

  • Wind power is the the largest source of sustainable energy in the United States. Wind power is now responsible for about 8.4 percent of all energy sources generated in the country
  • Solar. Wind and solar power represent the two fastest-growing sources of power in the United States
  • Hydro. Water within lakes rivers and the sea.

What is the biggest source of energy?

 One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.

What country is 100% renewable?

Iceland power generates close to 100 percent of its electricity from renewable energy, using their abundant geothermal and hydro supplies.

Which country is the largest producer of solar energy?

China –205 GW. China boasts by far the world's largest installed solar energy fleet, measured at 205 GW in 2019, according to the IEA's Renewables 2020 report. Inthe same year, power generation from solar energy totalled 223.8 terawatt hours(TWh) in the country.

Which country uses the least renewable energy?

Can 100% renewable energy power the world?

Electricity from solar, wind, and water could power the entire world in less than 10 years, leading energy experts say. Renewable energy could also be the sole energy source for the world's heating, cooling, transport, and industries by 2035.

Is there a future in renewable energy?

Renewable energy resources make up 26% of the world's electricity today, but according to the IEA its share is expected to reach 30% by 2024. Overall, renewable electricity is predicted to grow by 1,200 GW by 2024, the equivalent of the total electricity capacity of the US.

Is renewable energy a good career choice?

The energy industry is considered as highly capital intensive along with the huge impact on employment. Hence, the renewable energy field promises a lot in terms of sustainability and jobs prospects. The energy sector provides excellent career opportunities for smart and innovative minds.

What is the best type of renewable energy UK?

Figuring out the best source of renewable energy will depend on which one is right for you and your household's energy use.

The best type also comes down to which factors you prioritise, which could be your budget, energy efficiency or reducing your energy bills, so there's a lot to consider. However Solar power is probably the most effective. You can use the sun to generate electricity for your home through solar photovoltaic panels that are installed on your roof.

How will renewable energy affect my EPC rating at home in the UK?

How will renewable energy affect my EPC rating at home in the UK?

Not only can renewables provide clean and cheap energy but they can also greatly improve a property’s EPC rating. A popular way of doing so is Solar PV Systems actually count towards your EPC rating, and can often higher the grade you received to the next band. For example, a 4KW system can add up to 15 points to your EPC rating, meaning if you started at a low level E, after installation your property would then be a low level D

In Summary...

The one thing that having offered our readers this short list about renewable energy sources is that as a country and as individuals that we need to be picking up the speed and interest and reducing the cost of these newer technologies to enable us to offer our children’s children a better future and a more environmentally better world.

We may well have some of the oldest and least energy efficient properties in the world and a climate that is not always as sunny or as nice as we would like it to be but as a country, we should be more inspired to make the changes that are needed.

As a foot note and our own interest the UK is ranked sixth in the World for wind and solar electricity generation. Offshore and onshore wind is the biggest source of renewable energy in the UK. It not only beats the other renewable sources by nearly14% of total electricity generation in the UK. it also beats the combined generation of coal, oil, and others by nearly 7%.
