ENERGY STARs for renewables have soared in recent years as countries around the world have embraced clean energy sources.
But some have begun to question whether their growing popularity will result in more carbon emissions than the ones from coal and natural gas.
That’s the message from the latest findings from the U.S. National Renewable Energy Laboratory, a nonprofit research group that publishes an annual report on the economics of renewable energy.
The results, released Wednesday, show that while the use of renewable sources has exploded, their carbon footprints have not.
And they show that in some countries, it’s even worse.
The report, released with a focus on energy efficiency and renewable energy production, finds that the emissions from U.K. wind turbines, for instance, could account for half of U.L.G.s carbon footprint.
That makes the U,K.
the world’s largest wind power producer.
But in some ways, the report shows, that success is tempered by the fact that many of the turbines in the country aren’t particularly efficient or efficient at capturing carbon dioxide.
The U.A.E. also found that U.H.A.’s solar photogenerators account for one-third of its carbon emissions.
And the UH.
L.’s energy efficiency program accounts for a fifth of its emissions.
The study comes as the U-K.
government has announced plans to phase out its reliance on coal and other fossil fuels by 2030.
But the government has also promised to help developing countries transition to clean energy.
