What do we mean by 100% renewable electricity? All our customers' homes and businesses get 100% renewable electricity, at no extra cost.
If the world transitioned out of fossil fuels, could we generate the energy needed to power the world on 100 percent renewable energy? According to a new report by LUT University in Finland and Energy Watch Group, a German nonprofit, the answer is yes.
Desalination of seawater is considered a renewable source of water, although reducing its dependence on fossil fuel energy is needed for it to be fully renewable.
For a fully renewable tariff, with 100% renewable electricity & gas, we can find just one supplier – Green Energy UK. Yet for a typical user it's over £225/year more than the average big six standard deal at a whopping £1,351/year.

Octopus Energy score an impressive 4.8 out of 5 stars at TrustPilot (from over 65,000 Octopus Energy reviews), with 90% of the reviewers rating them as excellent. Only 3% of the reviewers rated them poor or bad. This places Octopus Energy in 5th place out of the 76 energy suppliers on TrustPilot.
EON has become the first big six energy company to ditch fossil fuels — sort of.
Our green tariffs match 100% of the electricity you use with electricity from renewable sources. If you're a gas customer, we offset your carbon footprint by supporting carbon emission reduction projects in the developing world. We do this by purchasing Certified Emissions Reduction certificates or CERs.
Nuclear energy is usually considered another non-renewable energy source. Although nuclear energy itself is a renewable energy source, the material used in nuclear power plants is not. Nuclear energy harvests the powerful energy in the nucleus, or core, of an atom.
Renewable energy sources are defined as renewable non-fossil energy sources: wind, solar, geothermal, wave, tidal, hydropower, biomass, landfill gas, sewage treatment plant gas and biogases.
The most popular renewable energy sources currently are:
Solar energy. Wind energy. Hydro energy. Tidal energy.EDF Fuel Mix
| Coal |
|---|
| Renewable |
| EDF's fuel mix | 20.5% |
| Contribution to our carbon emissions | 0.0% |
| UK average fuel mix | 37.9% |
Renewables generated 43 per cent of the UK's electricity, while fossil fuels provided 38.5 per cent. Offshore and onshore wind accounted for 24.2 per cent in the renewables share: offshore wind 13 per cent and onshore wind 11.2 per cent.

Large commercial vessels, such as cargo ships, generally operate on HFO while smaller ships, such as tugs and fishing vessels, tend to operate on distillate fuels, such as marine diesel oil (MDO), marine gas oil (MGO), or even ultra-low sulfur diesel fuel (ULSD).
Industry has been promoting hydrogen as a reliable, next-generation fuel to power cars, heat homes and generate electricity. It may, in fact, be worse for the climate than previously thought. It is seen by many as the clean energy of the future. “What we found is that it's not even a low-emissions fuel, either.â€
The energy source for the propulsion of ships has undergone significant transformations over the last 150 years, starting with sails (renewable energy) through the use of coal to heavy fuel oil (HFO) and marine diesel oil (MDO), now the dominant fuel for this sector.
Zero-carbon ammonia can be used to power ships and make the transport sector greener, a policy briefing by the British Royal Society shows.
Powering vessels with hydrogen can be done via combustion engines, blending hydrogen in with other fuels, or storing it in a liquid organic solution or as ammonia. The most common and greenest way of generating power from H2 is using hydrogen fuel cells. This is also what the MarHySafe project has focused on.
Using hydrogen fuel risks locking in reliance on fossil fuels, researchers warn. Fuels produced from hydrogen can be used as straight replacements for oil and gas and can be low-carbon, if renewable electricity is used to produce these “e-fuelsâ€.
Currently, most hydrogen is produced from fossil fuels, specifically natural gas. Electricity—from the grid or from renewable sources such as wind, solar, geothermal, or biomass—is also currently used to produce hydrogen. In the longer term, solar energy and biomass can be used more directly to generate hydrogen.
Ammonia has been produced and utilized for the past 100 years as a fertilizer, chemical raw material, and refrigerant. Ammonia can be used as a fuel but there are several challenges in ammonia combustion, such as low flammability, high NOx emission, and low radiation intensity.
The amount of fuel actually be used on a sailing depends primarily on the ship's speed. Most ship engines have been designed for top speeds ranging between 20 and 25 knots per hour, which is between 23 and 28 miles per hour. A Panamax container ship can consume 63,000 gallons of marine fuel per day at that speed.
