a bright idea: how changing light bulbs helps beat global warming (and cut bills)
In the next 25 years, energy bulbs and other efficient lighting systems can prevent the cumulative 16 billion tons of carbon from being added to the world\'s atmosphere, according to a report from the International Energy Agency.
The agency says it does not need any technology that is not yet widely available.
Far from spending money.
It will save more than 1, 300bn.
The light used by homes and offices is the main cause of climate change and can also cause \"light pollution\", meaning that urban children will never see the stars.
The British government alone has 50,000 buildings, with a total energy bill of nearly £ 200 a year and emissions of 0.
75 tons of carbon per year.
Most of these buildings use inefficient lighting systems.
Two years ago, all government departments received instructions to improve energy efficiency. but the 12-
Energy is not specifically mentioned in the page framework file --
Efficient lighting system.
However, when Tony Blair had a low profile, he did make a symbolic gesture towards efficient lighting
The energy bulb installed in the lamp outside the 10th Downing Street.
Environmental activists believe politicians must take the lead in enforcing the technology.
Stephen Tindale, executive director of Greenpeace UK, wrote in The Independent: \"We don\'t have time for individuals to save the world. . .
Governments must act to ensure that we see peaks and declines in global carbon emissions over the next 10 years.
Otherwise, we will face serious risks of runaway global climate.
\"Artificial light accounts for almost one.
The world\'s fifth largest electricity consumption, far more than the power generation of all nuclear power plants in the world.
It produces about 1.
The annual value of 9 billion tons of carbon is equivalent to nearly three quarters of carbon emissions from all cars and light vehicles in the world.
This is just the beginning of the problem.
Within 25 years, as the developing world moves towards a Western standard of living, the global demand for light-making is expected to be nearly double that of today\'s level.
The average artificial light used by American families is 10 times that of Chinese families and more than 30 times that of Indian families.
And there are 1.
6 billion people in the world have no electricity at all.
The International Energy Agency says the amount of carbon from standard bulbs could increase to 3 billion tons a year.
\"Without quick action, energy for lighting in 2030 will be 80 higher than today,\" said Claude Mandir, executive director of IEA . \".
\"However, if we can make better use of today\'s efficient lighting technologies and technologies, there will be no greater global demand for lighting energy.
The \"Light\'s Labor\" report adds to the debate launched a year ago at the G8 summit in Gleneagles.
\"When considering operating costs, they save a lot more money on the avoided energy bills than the cost,\" the report said.
The British Federation of lighting industries said that \"a large part of the UK\'s lighting equipment, if not most, uses inefficient systems, efficient bulbs and controls can reduce the average bill by 30 without reducing the amount of lighting.
The proposal through the International Energy Agency will end the standard incandescent lamps that have been in use since 1880.
Light bulbs like this emit almost 20 times as much heat as light, and the report warns that additional air may be needed
Regulating energy for heat dissipation.
Efficient Lighting is clearly a good idea, and the authors of the report say it is difficult to explain why common sense and market forces are not combined to achieve this.
But they point out that the cost of efficient lighting will be higher in the short term.
The best system has the cost of installation, and the people who install the lighting system are not the same as the users who pay the bill.
The report from the International Energy Agency says the government should take the lead by better regulating the market and incorporating lighting systems into building regulations.
China has recently enacted a regulation that, if implemented in every new building in China, will \"offset the need for a new Three Gorges Dam project every eight years \". Energy-
