How to deal with snow on solar PV modules

This past weeks little deluge of snow may have provided a nice seasonal blanket of white over your solar PV modules.

Six steps to claiming £400 for a new boiler

Households with inefficient, old boilers (G-rated) can get £400 off the price of a new A-rated boiler thanks to the new boiler scrappage scheme launched yesterday by Gordon Brown and Ed Miliband. You can also put the money towards a renewable heating system such as a biomass boiler or heat pump. …

Is it worth insulating under the floor boards?

Around 15% of the heat leaving a house exits through the ground floor. And that does not account for the draughts coming up through the floor. So the simple answer is Yes - it is worth insulating under the floor boards. The problem is that, unless you have space to get under the floor boards, it …

Give the gift of light this Christmas

Give the gift of light this Christmas

We talk about fuel poverty here in the UK, but it's nothing compared to places like Africa, where people spend 15 to 20% of their income on kerosene. Not only is it expensive, but kerosene is also the main source of poison in Africa. Solar power has the potential to bring the gift of light to ma…

Can you heat a house with a wind turbine?

Can you heat a house with a wind turbine?

A reader has asked if it is possible to heat a house with a wind turbine. The simple answer is that it is possible, but it's unlikely to be the best solution. Heating demand depends on the construction of the home and the weather. A home requiring a 13kW boiler will need a maximum of 13 x 24 kWh …

Potential for energy bill savings are huge

If new boilers were installed in all homes sold in a year, where recommended in the energy performance certificate, it would lead to total cash savings of almost £80 million on energy bills. On the same day last week that the Chancellor announced the boiler scrappage scheme in his pre-budget rep…

The wettest winter for years

The wettest winter for years

With all the rain we've had recently, it's difficult to convince people that water really is in short supply for some of us. However, what we need to consider is where does it all go, and why, if it's so wet, is it scarce? To answer those questions very briefly: 1. Population is increasing, as…

An introduction to solid wall insulation

An introduction to solid wall insulation

A third of the heat lost from a house is through the walls according to the Energy Saving Trust. An uninsulated, 225mm solid brick wall will have a U-value of 2.23W/m2. Adding just 50mm of PUR (Kingspan or similar) insulation will reduce that to just 0.4W/m2. Bear in mind that the current buildin…

Feed-in rate announcement may be delayed

The much awaited results of the consultation on feed-in tariffs may take a little longer than hoped. Internal wrangling between government departments is to blame according to the Guardian, and it's not clear when we're going to find out. Ed Milliband had apparently hoped to have the policy i…

Learn how to build your own wind turbine

As a nation of DIY fanatics it's surprising that more of us aren't getting out there and building our own renewable energy. Given the rapid increase in energy prices this century, and that DIY solar hot water kits and courses are popular in Austria and Germany, I'd expect more people to be doing it.…
