Where Has The Water Gone?

Image
Two headlines caught my attention today. The first was from Tuesdays Glasgow Evening Times: Save water plea ... after wet summer It was about Scottish Water's recently launched campaign to encourage people to save water. The reason for this campaign is not a shortage of water but a drive to save energy in treatment and pumping of the water. While I do support any measures that we can take to reduce energy use and carbon emissions, I feel that this is Scottish Water trying to pass the responsibility on to the public rather than dealing with their own wasteful inefficiencies.  They lose more water through leakage than the total domestic consumption, as noted here , so whatever individuals do to save a little bit of water is nothing compared with the amount leaking from pipes.  The volume of water lost through leakage will not reduce even if the volume used by consumers is reduced significantly, in fact it may increase as the pressure in the sy...

The Changing Seasons

There was a nip in the air this weekend as the season begins to change and, if we needed it, a timely article in this Sunday's Independent serves as a reminder of some of the things we can do to save energy over the autumn and winter. The ten suggestions from the Independent are summarised below with some comments and a few other suggestions of my own: 1. Small changes - with emphasis on energy saving lightbulbs: Incandescent light bulbs are no longer available for domestic use so we should all be using low energy bulbs now or in the near future. 2. Efficient heating - ensure your radiators are working effectively and aren't blocked by furniture. Upgrading your boiler is also suggested but this can be a significant financial investment. The savings from upgrading your boiler depend on how inefficient the old one was and there may be other more cost effective energy saving investments. 3. Keep the heat in - draught proofing, loft insulation, cavity wa...

Electric Cars

Image
Glasgow is a compact city.  Nowhere in the city is much further than 10 miles from any where else.  It is perfect for electric vehicles(EVs) which typically have a short range. Pictured above are two of the forty electric vehicles being trialled by Glasgow City Council.  The trial which began over a year ago is scheduled to run for three years.  The vehicle fleet operated by the City Council comprises over 1200 vehicles of which over 350 are cars or car derived vans with the remainder including everything from small vans to bin lorries, minibuses and even articulated lorries. This is surely a welcome measure to reduce the city's carbon footprint and improve air quality. Or is it?

Solar Electricity Tariffs

"Homeowners will have to spend more to qualify - http://t.co/VMFcsHrc - but we do need to prioritise." @EcoWarriorMe The recent announcement by the government to cut feed-in tariffs for solar electricity generated by householders has quite rightly faced heavy criticism. Installation of solar panels under the scheme has led to significant growth in the sector, creating employment as well as green electricity. Changing the goal posts at short notice jeopardises this genuinely sustainable economic growth but it also undermines confidence in any future initiatives. Another part of the changes to the feed-in tariff is to restrict the scheme to homes that are already energy efficient but this is not necessarily a bad thing. "Some 86% of the UK’s homes do not meet the ‘C’ energy rating standard that properties will need to qualify for the feed- in tariff"  The Guardian In homes with a poor energy rating, it is cheaper to implement energy saving measures than to overa...
