Switch to a green renewable energy supplier


Switching to green energy is one of the easiest and quickest ways to reduce your carbon footprint. There are many on-line services that allow you to quickly and easily compare green energy tariffs to get the best deal in your area, and start saving money on your energy bills.

There are many online services which help you switch to a ‘green tariff’ with all of the Big 6 energy companies now offering a green tariff however, chose your supplier with caution as some are more ‘green’ than others. Some suppliers simply decrease the amount of renewable energy other clients receive so yours appears more ‘green’ however, in reality, you are not contributing to additional renewable energy capacity, they are simply making everyone else’s energy more ‘brown’.

For maximum benefit, we suggest you chose a supplier who can prove that all the renewable energy they sell is produced by themselves on sites which they own.

Have a look at this Which article on “How Green Is Your Energy Tarriff?” or this article by the Energy Saving Trust which suggests some good suppliers.

Turn the heat down


Reducing your room temperature by 1°C could cut your heating bills by up to 10% and save you around £50 per year. If every household in Devon turned their thermostat down by 1°C, we would save 75,000 tonnes of CO2 every year.


Insulate your home


Houses that aren’t well insulated need to use more energy to keep warm. Not only does this cost you more money, it also creates a much larger carbon footprint – especially if you aren’t on a renewable tariff!

While the initial insulation may require a bit of investment, it will pay off in the long run with lower bills, a more efficient home and a smaller carbon footprint.


Check out this advice sheets from the Centre for Sustainable Energy which cover how to insulate your home’s walls, floor and loft and reduce heat losses from doors and windows.

LED Lightbulbs


There are two main types of energy efficient light bulbs available. Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs).

CFLs are what you typically think of as an energy efficient light bulb. CFLs are a cost-effective option for most general lighting requirements. Replacing a traditional light bulb with a CFL will save you around £3 per year, or £50 over the lifetime of the bulb.

LEDs though more expensive to buy initially, are more efficient than CFLs and will save you more money in the long term. Replacing a halogen spotlight with an equivalent LED will save you around £4 each year, or £140 over the bulb’s lifetime.

If every household in Devon swapped two normal 60 watt bulbs for low-energy ones, we’d save over 100,000 tonnes of CO2 emissions. 


LED bulbs can be bought from all major retailers.

Read this advice sheet from Centre for Sustainable Energy on LED lightbulbs.

If you are eligible or at risk of fuel poverty, LEAP may be able to offer you free LED bulbs to help reduce your fuel bills.
