Cheaper energy is not the solution

Dear Editor,

In December Chris Huhne, the energy and climate change secretary, set out a number of proposals for providing ‘lower-carbon electricity at lower cost than under present policies’. No one in their right mind would argue for higher-carbon forms of energy, but is he right to focus on lowering the cost?

Cheap energy, like cheap food, comes at a price. We should be using the tax system to drive up the cost of wasted energy and encourage not just energy-saving but energy efficiency in the fairest way possible. When energy prices are high, people are both more careful and more disciplined about how they use it.

Greater use of controls and metering can supply part of the discipline, as can the expertise from lighting designers – but only if designers are free to do their jobs without restrictions.

We have been too lax on energy for too long but there is also a tendency to micro-manage in areas such as the Building Regulations. Surely

this government above all should recognise the value of applying market pressure through pricing while applying a light touch to regulation.

Yours faithfully,

Photometry – some common misconceptions cleared up

Dear Sir,

I read Alan Tulla’s feature in the July issue ‘Why all LED downlights are 100% efficient’ which referred to the fact that LED luminaires have an LOR of 100.

London Lighting the unseen buildings

Dear Editor,
Pick up any magazine and there are photos of wonderfully lit buildings by the UK’s top designers. For those without a designer, there is plenty of advice in the series of Lighting Guides produced by the Society of Light and Lighting.
