The cost of green energy efficiency

No one ever said concern for the environment was going to be cheap.

The Energy Secretary, Ed Miliband, announced last week that Britain becoming a low carbon-economy will cause the average annual energy bill to rise by as much as £92 a year by 2020. Figures from the UK Energy Research Centre show the increase could be closer to £230. However, making your home more energy efficient can cut your bills although, in most cases, upfront costs are unavoidable.

Compared to countries on the continent, the housing stock in the UK is old. A large proportion of properties have been around more than 60 years and are leaking heat all over the place. However, improvements can be made.

A high-efficiency boiler coupled with solar thermal panels can reduce heating bills. Solar thermal panels installed facing south will produce as much as 30-40 per cent of the power needed to heat your water annually. However, according to the Energy Saving Trust, a standard system will cost from £4,000 to £6,000 to install, meaning it will take between seven and 14 years to recoup the investment.

As fuel prices rise, investing in a more energy efficient property will be more rewarding. “Over and above the environmental concerns, we need to think about fuel supply,”. “If you want to secure against increased heating and electricity costs, then being more efficient in your home is the way to go.”

Sainsbury's brings green power to the checkout with 'kinetic plates'

A supermarket chain will open its first "people-powered" store this week using technology that captures energy from vehicles to power its checkouts.

In a European first, Sainsbury's will install the invention at its new store in Gloucester, opening this Wednesday.

Energy will be captured every time a vehicle drives over "kinetic road plates" in the car park and then channelled back into the store.

The kinetic road plates are expected to produce 30 kWh of green energy every hour — more than enough energy to power the store's checkouts. The system, pioneered for Sainsbury's by Peter Hughes of Highway Energy Systems, does not affect the car or fuel efficiency, and drivers feel no disturbance as they drive over the plates.

Alison Austin, Sainsbury's environment manager, said: "This is revolutionary. Not only are we the first to use such cutting-edge technology with our shoppers, but customers can now play a very active role in helping make their local shop greener, without extra effort or cost.

"We want to continue offering great value but we also want to make the weekly shop sustainable. Using amazing technology like this helps us reduce our use of carbon and makes Sainsbury's a leading energy-efficient business."

The kinetic road plates are one of a number of energy-saving measures at Sainsbury's new store in Gloucester Quays, Gloucester. The store will harvest rainwater to flush the store's toilets and solar thermal panels will heat up to 100% of the store's hot water during the summer, and more than 90% of the construction waste was re-used or recycled.

David Sheehan, director of store development and construction at Sainsbury's, said: "The new environmental features within the Gloucester Quays store mark a very exciting time in store development. We are able to use cutting-edge technology to improve our services and the store environment for our customers and colleagues, at the same time as ultimately reducing our carbon footprint across the UK."

Claim solar panels grants – but do it now

GREEN support services provider eaga is urging local authorities and housing associations across the UK to apply for funding from the Low Carbon Buildings Programme before it runs out next year.

The Government-funded scheme encourages the take up of low and zero-carbon energy sources. It will match fund up to 50% of the cost of installation projects to a maximum value of £1m.

But applications must be made by June 2009 and the cash must be spent by June 2010.

FTSE 250 eaga has considerable experience in facilitating access to the Low Carbon Buildings Programme funds and fitting renewable energy sources such as solar thermal panels.

It has worked with numerous local authorities and housing associations across the UK and has recently helped launch a renewable energy education programme for local students by donating a solar demonstrator panel to Yardleys Science College in Birmingham.

Steve Caseley, managing director of eaga Renewables, said: “The Government recently increased the Climate Change Bill targets for reducing the UK’s greenhouse emissions from 60% to 80% by 2050.

“While this positions the UK at the forefront of efforts to tackle climate change – it will also dramatically ramp up the pressure on local authorities and similar organisations to cut their carbon emissions.

“Securing funds from the Low Carbon Buildings Programme can help meet these demanding targets. Indeed, if organisations get their renewable and low carbon energy management right, they could also tap into exciting opportunities ahead through potential feed in tariffs. Hospitals, for example, could create their own renewable or low-carbon power source and then sell any surplus back to the national grid.

This already happens in other European countries and every indication is that the same will happen here.”

Using the sun as a renewable power source, solar thermal panels can convert enough heat to provide up to 60% of a typical household’s hot water needs. A 4sq m panel can also cut annual CO2 emissions by up to a tonne.

Even in overcast conditions the solar panels can still absorb up to 65% of available energy.

For local authorities and social housing providers they can therefore offer an extremely economical and efficient source of renewable energy, particularly for homes or properties which have no access to mains gas or which are in remote rural areas and hard to reach.
