According to recent news from UK, “Climate change: LED lights making dent in UK energy demand”. Installing a single low-energy LED bulb may make a small contribution to reducing the carbon emissions of the Earth’s overheating. But if millions of people choose LED, their efforts will have a small but significant impact on Britain’s energy demand. Research shows that making products more efficient — and other factors — in reducing carbon dioxide emissions has been slightly more effective than renewable energy. The difference is that fascinating renewable energy dominates the headlines. However, the “Cinderella” field of energy efficiency is often ignored or ridiculed.check here
How much carbon would be reduced?
As we all know, the huge shift from coal to renewable energy has helped Britain achieve its ambition to cut carbon emissions. The report says that from 2005 to the present, the use of renewable energy has decreased by the equivalent of 95 terawatt-hours of fossil fuel energy.check here Last year, renewable energy accounted for 33% of UK electricity generation, a record.
But at the same time, inefficient energy efficiency has reduced energy demand by 103 terawatt hours. In other words, in the carbon emission reduction competition, efficiency has won so far. Moreover, efficiency is indisputable, unlike wind and solar energy.check here
