Creating the green dream

Creating the green dream

Converting your house to low-carbon luxury doesn’t come without a lot of hard work, and vast quantities of attention to detail. Last week I wrote about what Sue Harley and Neil Tappenden achieved in turning their Devon farmhouse into a low-carbon dream home. This week I look at how they did…

Grants for Solar PV projects on community buildings

Grants are in the news again! The tranche of cash recently added to the Low Carbon Building Programme phase 2 looks likely to be exhausted towards the end of this month. If you have a community project that requires funding from this programme, my advice is to make sure that you get the application …

Is bigger better?

Is bigger better?

Renewable energy can be a little confusing. For example, explaining to some people that doubling the size of a solar thermal system isn't necessarily a good thing, but doubling the size of a solar PV system is; doubling the size of a heat pump isn't a good idea, but doubling the size of a wind turbi…

Living the green dream

Comfort and beauty don’t have to go out of the window in pursuit of energy efficiency and low carbon living. It is possible to live in beautiful luxury, with barely a fossil fuel involved. Banish all thoughts of The Good Life, I know it’s true, I’ve just seen the evidence. R…

Who makes wind turbines in the UK?

Who makes wind turbines in the UK?

One of the nicer things about the wind industry, especially the small wind industry, is that there are still only a relatively small number of manufacturers and distributors in the UK, so you can get a good feel for the market quite quickly. In the sub 10kW range, the most successful companies a…

Evacuated tubes: make sure you don’t get burnt

Posted by Gabriel Wondrausch on 4 February 2009 at 8:34 am

Evacuated tubes: make sure you donât get burnt

Evacuated tube collectors are the Formula One of the solar thermal world. They are more efficient than other types of collector as they are almost perfectly insulated, and heat cannot pass through a vacuum. As the tubes are cylindrical, they are always perpendicular to the sun reducing the amount of…

Good Energy rewards renewable heat generators

Posted by Cathy Debenham on 3 February 2009 at 10:42 am

Solar thermal panels to heat your water just got more attractive with the launch of Good Energy's renewable heat incentive, or HotROC, contract. This means that customers who generate heat or hot water from renewable sources are paid for the energy they create. This is a first step towards pu…

How to store heat in a thermal store

How to store heat in a thermal store

Only a serious biomass nerd can get excited about thermal stores. Sadly, I count myself as one of those people. First of all what is a thermal store and what does it do? Essentially it’s a large water tank (usually round) which is well insulated with a series of bosses to connect pipes …

Optimising solar pv siting

Optimising solar pv siting

It’s obvious that solar PV systems need as much sunlight as possible – so the ideal is to position them at about 37 degrees to the horizontal (in the UK) and facing due South. Even better, if you can afford one, are tracker systems that ensure the modules follow the sun through the sky – altho…

How much do you spend on heat and power?

How much do you spend on heat and power?

Gas and electricity bills gobble up a significant chunk of income for most of us, but do you know how much you're spending week to week? I didn't, until a few months ago, when I discovered imeasure. By just putting a weekly reading into the site, I can find out how much I spent last week on gas…
