There are two main types -- air source heat pumps, which extract heat from the air, and ground source heat pumps, which extract heat from the ground -- and both work essentially like the reverse of a refrigerator. Last year, the UK installed more than five times fewer heat pumps than Lithuania, more than 30 times fewer than Estonia and 60 times fewer heat pumps than Norway, the Greenpeace analysis showed. While some countries, like the UK, celebrate their phase-out of coal, they are using more gas -- but natural gas isn't exactly a low-emissions fuel either. Research by the Yale Program on Climate Change Communication, published this month, found that calling it "natural" gas influenced public perception. While feelings about "natural gas" were positive among the 2,931 American adults surveyed, feelings about "natural methane gas" were neutral, and feelings about "methane gas" and "methane" were negative.
