San Diego fires, 3

Just one of the San Diego fires (the Harris fire) has burned an area equal in size to Lewes District. The Harris fire isn't even the largest fire: the Witch Creek fire is two and half times larger - almost the size of Wealden District.

A photo of the San Diego fires. Evidence of global warming? No, no single event is. However, climate models do predict an increasing frequency of such fires (remember the Greek fires, recently). As temperatures increase, the ground is more frequently dry, winds are higher, vegetation is drier.

Peak tungsten?

Here's some good news for the environment. General Electric are shutting down production of traditional light bulbs, in favour of low energy light bulbs.

I hope (but somehow doubt) that they're looking after the employees.

In case your in doubt about low energy bulbs, the technology has come a long way in the last few years, and is improving rapidly. So, you can get bulbs with the same light quality as traditional bulbs, they fit a wide range of lamps (including halogen spots), and they can start instantaeously. So, there's no real reason to not use them.

The savings make it a no brainer - a conventional bulb will work for about 1,000 hours (if you work full time, you might work 2,000 hours per year). In that 1,000 hours, a 100w bulb will use 100 units of electricity. That's about £10 worth. An equivalent low energy bulb will last 5,000 hours, and cost from £2 to £10, while using a quarter of the electricity (about £2.50 per thousand hours). So, it will pay for itself in the first 1,000 hours, and by the time you have to replace it, will have saved you about £37 in electricity - that's probably enough to pay for a new light fitting, if you need one.
