摘要：Nearly 130 years after Thomas Edison invented it, the world may be on the
brink of saying ‘thank you, and goodnight’ to the incandescent electric light
bulb. Australia has announced a ban; Cuba, Venezuela and the European
Union are among those moving in the same direction. We should celebrate
its demise, for the world’s billions of bulbs — only five per cent efficient at
converting power into light — cause massive emissions of carbon dioxide.
Of course, dealing with climate change requires governments to regulate on
emission reduction targets and promote more sustainable forms of energy
generation and consumption. But part of the solution also lies around the
corner at the local shop or supermarket, just as much as in international
conference halls. This message — that the power to act rests as much with
consumers as with ministers and heads of state — is emphasized by World
Environment Day, which this year is being hosted by the Government of
Norway in the Arctic city of Troms..
