Green party promises best finance scheme for microgeneration

Proper insulation for every home and interest-free loans for domestic renewable energy are just some of the policies promised by the Green party if they win the next election. While it would be expensive, says Paula Black, Totnes councillor, and prospective Green Party parliamentary candidate for Ex…

Solar panels fall in price

Solar panels fall in price

There is both good news and bad news in the solar PV (photovoltaic) installation world. Over the last few months, the cost of solar electricity modules has fallen by anything up to 10%. This is due to an early year slump in demand throughout Europe in caused by the credit crisis. There had also b…

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.…

Renewable heat soon to join the energy revolution

Posted by Gabriel Wondrausch on 6 November 2009 at 9:13 am

Renewable heat soon to join the energy revolution

Until a few months ago, solar thermal hot water heating has been the most cost effective way for people to generate their own renewable energy - for every pound invested it has usually delivered the highest units of energy. The reason for this is that solar thermal systems have always been the most…

Sash windows can be made energy efficient

Traditional timber sash windows are often associated with howling draughts, and are under threat as people replace them with plastic double glazed units. But before you throw yours on the scrapheap, read English Heritage's research which shows that simple repairs and basic improvements can significa…

How noisy are wind turbines really?

How noisy are wind turbines really?

When discussing noise and wind turbines it is important to be clear what size of turbine you are thinking about. The noise from large, commercial wind turbines is very different to that generated by smaller turbines installed at homes, offices and schools. The rotors on smaller turbines rotate much…

Act now if you want to measure wind speed

Act now if you want to measure wind speed

Measuring the wind speed on your potential site is the only sure fire way of knowing how good an investment a wind turbine will be as regular readers of the YouGen renewable energy blog will know.  Until recently this wasn't either cheap or easy, but that changed earlier this year with the l…

Will it cost me more to harvest rainwater?

Posted by Barry Nutley on 26 October 2009 at 2:32 pm

Will it cost me more to harvest rainwater?

Rainwater harvesting systems tend to be pumped, causing people to ask the following questions : 1. "Does the cost of running the pump negate any savings made?" 2. "By running a pump, are we increasing our carbon emissions, and negating any environmental benefits?" Well, to answer those…

At last some vision and ambition from a government scheme

Encraft is fortunate enough to be involved in the government's Retrofit for the Future competition. This is a national scheme to find innovative ways of reducing carbon emissions from housing by 80% or more – something we urgently must to do to deliver the carbon dioxide reductions we need. Wha…

Energy: out of sight, out of mind?

Energy: out of sight, out of mind?

This week is Energy Saving Week, so it seems as good a time as any to think about energy and what it means to us. Despite the constant calls on us to be more energy efficient, the reality for most people is that we know next to nothing about our energy consumption. Most of us have a grasp of how …

Making the most of passive solar energy

Posted by Tim Pullen on 14 October 2009 at 9:24 am

Making the most of passive solar energy

Using passive solar energy is a matter of design. To put it another way, if you don't design the house to use passive solar energy, it is difficult to use it well. So pretty much the same as any other form of energy then. What you need is three things; thermal mass (something to absorb …

Whole house approach to energy efficiency needed

Government must make a major shift in policy to transform the energy efficiency of our residential housing stock according to the Committee on Climate Change's first annual report. A whole house, street by street approach in which  households are offered an energy audit, with a follow up pac…

Learn how to generate your own electricity

Wind farms - you either love them or you loathe them. I'm on the side of love. Ever since the first time I drove down the A395 in Cornwall, and they loomed, eerie and magnificent in the bleak dusk, I've been a wind turbine fan. So I'm excited to hear about Good Energy's Power from the People day …

Building a thermal store - experience sought

Building a thermal store - experience sought

Can anyone help Jeff B with this query: I am thinking of having a very large thermal store (of the order of 2000 litres capacity) to use with my 30kw wood pellet boiler. Due to space restrictions this would have to be located just outside the house. Does anyone have experience of making a wel…

Rainwater harvesting: small is beautiful

Rainwater harvesting: small is beautiful

When we think of rainwater harvesting, we tend to envisage a full scale domestic system with a large tank, say 4000 litres, buried underground, providing water to the toilets, washing machine et al. This can be a costly business (especially if it's a retrofit project) with not much change from £7,0…

Equal feed-in tariff for existing generation has heavyweight support

Support for equal feed-in rates for those who already have small solar PV, wind turbines or hydro came from diverse parts of the renewable energy sector at yesterday's RegenSW conference in Bristol. Sponsor Christine Griffiths of Aeolus Power got her passionate call in early in the day - to be me…

Island grid increases energy security aspect of microgeneration

Island grid increases energy security aspect of microgeneration

Security of electricity supply is one of the main reasons that people install their own solar panels or wind turbine. However, a system that is connected to the national grid currently doesn't afford total control. The benefit of grid connection is that you can sell any excess you generate to the…

Solar PV: how to tell the difference between panel types

Solar PV (photovoltaic) panels come in lots of different types - mostly with long and complicated names - so it's not easy to know what the difference is. Last night I went to an excellent evening organised by the Sid Valley Energy Action Group - a group of enthusiastic volunteers who promote ene…
