The total available capacity from wind, solar, biomass, hydro and other renewables reached a record 42 gigawatts between July and September, overtaking the 40.6 gigawatts available from fossil fuels, according to a report commissioned by Drax's Electric Insights and produced by Imperial College London researchers.
A first-of-its-kind study published Monday shows that, when it comes to impacting life on Earth, humans are punching well above our weight.
The study, published in Proceedings of the National Academy of Sciences, is the first ever comprehensive census of the distribution of the biomass, or weight of living creatures, across classification type and environment. It found that, while humans account for 0.01 percent of the planet's biomass, our activity has reduced the biomass of wild marine and terrestrial mammals by six times and the biomass of plant matter by half.

Over the last several years, study after study has documented why burning trees to produce electricity, known as "biomass," will accelerate climate change. More than 800 scientists from around the world recently signed a letter to the EU government warning that burning trees for electricity releases more carbon into the atmosphere than coal per unit of electricity generated, increasing the amount of carbon in the atmosphere at a critical time when we must be doing everything we can to reduce it.
Costa Rica has charted another clean energy accolade. So far this year, the Central American country has run on 300 days of 100 percent power generation from renewable energy sources, according to the Costa Rican Institute of Electricity (ICE), which cited figures from the National Center for Energy Control.
With six weeks left of 2017 to go, Costa Rica could easily surpass 300 days.
For the study, researchers from Radboud University in the Netherlands, alongside their German and English colleagues, measured the biomass of trapped flying insects at 63 nature preserves in Germany since 1989. They were shocked to discover that the total biomass decreased dramatically over the 27 years of the study, with a seasonal decline of 76 percent and mid-summer decline of 82 percent, when insect numbers tend to peak.
