In Whitehall, advocates of PAYS and an expanded suppliers obligation are clashing over which mechanism should be used to refurb existing housing. This is the second post of two. If you missed it, read the first part here. Here’s a quick summary of the two mechanisms:

Hitting the 80% carbon reduction by 2050 has huge implications (and costs) for the residential sector. Two strategies are emerging for dealing with these costs, each with its own potentially severe side effects.
FiT as pants as expected – but holy smokes look at that RHI!
Posted in biofuel, biomass, chp, climate change, energy, engineering, feed in tariff, renewable energy, renewable heat incentive on February 1, 2010 | 6 Comments »
DECC have announced the final FiT levels in advance of the incentive coming in in April. Having had a number of disheartening conversations with policy makers over the last few months, the FiT levels are no surprise. No one in government seemed to mind that the FiT would be a subsidy for middle class greenies [...]
how much PV can you fit on a flat roof?
Posted in energy, engineering, feed in tariff, london, PV, renewable energy, zero carbon, tagged Volker Quaschning on August 14, 2009 | Leave a Comment »
Following on from discussion about planning reports last week, here’s a chart I put together showing roughly how much PV you can fit on a flat roof. It’s based on the formulas described by Volker Quaschning, the German Godfather of Sol (Thank you! I’ll be here all week. Try the crab). The shading angle is [...]
heat pumps emit more carbon than gas boilers – so why will they get the Renewable Heat Incentive?
Posted in DER Calculation, feed in tariff, heat pumps, renewable energy, sustainability, tagged David MacKay, renewable heat incentive, RHI on August 11, 2009 | 21 Comments »
The new SAP has a revised carbon intensity for grid electricity (set in the consultation at 0.591 kgCO2/kWh, up from 0.422). This has a big impact on the resulting carbon emissions from heat pumps, in most cases making them higher than emissions from the worst boiler you can legally install. This goes for both air [...]
planning reports may be ticking time bombs

For consultants, energy reports for planning are fantastic: a bit of SAP, a few benchmarks, some spreadsheet magic, and hey presto you’re sending an invoice. But the contents of the energy report can have huge implications, in some cases committing the scheme to commercially or legally impossible strategies, causing delays and increasing costs later in [...]
Sunday Times quote
Posted in climate change, Code for Sustainable Homes, other stuff, renewable energy, zero carbon on August 3, 2009 | 2 Comments »
Made it into the Sunday Times this weekend in an article titled Ed Miliband’s carbon neutral homes pledge in peril. Two things: first, I sometimes feel a little uneasy speaking to journalists because I might be selectively quoted – but I needn’t have worried. And second, it’s very interesting to see this sort of article [...]
document mania – reading roundup
Posted in climate change, energy, feed in tariff, renewable energy, sustainability, zero carbon, tagged Ed Miliband, Lord Hunt, Low Carbon Industrial Strategy, Peter Mandelson, Renewable Energy Strategy, UK Low Carbon Transition Plan on July 16, 2009 | 2 Comments »
Government launched a barrage of documents at us yesterday. I was mostly watching out for the Renewable Strategy but that was only a small part of it. Here’s the reading roundup: UK Low Carbon Transition Plan – this is the overarching doc. It’s basically the roadmap to meeting the legally binding carbon budgets from now [...]
LCBP back up and running
Posted in biomass, feed in tariff, renewable energy, sustainability, zero carbon on July 9, 2009 | Leave a Comment »
Good news. As spotted by Tom N, the LCBP Stream 2 is back up and running with £35m of new funds (and a hefty backlog of PV, GSHP, and solar thermal projects that weren’t processed before the money ran out the last time). One lovely feature: the cap for heat technology has gone from 45kW [...]
biomass supplier database
Posted in biomass, renewable energy, sustainability, zero carbon, tagged biomass energy centre on July 9, 2009 | Leave a Comment »
The Biomass Energy Centre has launched a national woodfuel supplier database. A couple of websites have tried to do this over the years but this one is already fairly well populated and it looks like BEC mean business.
