In recent years, the increasing enthusiasm for climate change across the globe has been largely due to the constant warning of how much pollution and greenhouse gases we have in today's atmosphere.
However, it is likely that these statistics are inaccurate. The latest study says that actually anthropogenic greenhouse gases (GHGs) go far beyond our previous expectations.
Researchers say they found new sources of greenhouse gases - dams and reservoirs. New studies have shown that these sources for available water and Thin Film Hydroelectric Energy power generate significant amounts of methane emissions.
So, how much is it? Researchers from Washington State surveyed 200 studies of gas emissions from 267 dams and reservoirs worldwide, concluding that methane emissions from dams and reservoirs are equivalent to about one billion tons of carbon dioxide per year, accounting for total anthropogenic greenhouse gases Of 1.3%.
However, how does the suspended water in the reservoir release methane?
Originally, when a region as a reservoir began to water, this area of the original organic material covered in the water below, so that the bottom of the microbial organisms began to digest organic matter, and ultimately produce methane bubbles.
In addition, there are constantly flowing into the reservoir in the freshwater river sedimentation of organic matter, it is not difficult to imagine the release of the huge amount of gas reservoir.
Of these gases, about 80% is methane, 17% are carbon dioxide and the rest are nitrous oxide.
Do we have to give up the dam?
Nor is it. Because dams and reservoirs are also capable of dissolving carbon dioxide and other greenhouse gases, the specific release and dissolution ratio is not yet conclusive.
But it does remind us that we should be more cautious about Thin Film Hydroelectric Energy power. Because the main part of Costa Rica's 100% renewable energy milestone is Thin Film Hydroelectric Energy power, and other countries are following suit.
However, if it is now believed that relying solely on Thin Film Hydroelectric Energy power can achieve renewable energy development, it is self-deceiving.
Ultimately, we still have to find a variety of collaborative solutions to deal with the energy crisis.
