QUICK NEWS, March 5: The Unrecognized Dinner Party Threat To Climate; New Energy Is Saving The World; New Energy Leaped Ahead In 2017 While Old Energy Dropped
The Unrecognized Dinner Party Threat To Climate Why what we eat is crucial to the climate change question; Our food – from what we eat to how it is grown – accounts for more carbon emissions than transport and yet staple crops will be hit hard by global warming
Ruth Khasaya Oniango, 5 March 2018 (UK Guardian)
“…[G]lobally, food systems account for roughly one quarter of all manmade greenhouse gas emissions. That’s more than the entire transportation sector, more than all industrial practices, and roughly the same as the production of electricity and heat…[T]he most immediate threat of climate change for most of the global population will be…our ability to grow critical staple crops…[Between 1980 and 2008,] wheat yields dropped 5.5% and maize yields fell 3.8% due to rising temperatures…[F]ood and agriculture are both enormous contributors to climate change, and massively impacted by it…[This] implores us to look beyond farm and agricultural practices…to solutions that address the full scope of the challenge to create more sustainable and equitable food systems…” click here for more
New Energy Is Saving The World New study upends conventional thinking about what’s driving down carbon emissions; Study comes on the heels of a Bloomberg New Energy Finance report that highlighted a similar trend.
Mark Hand, February 28, 2018 (ThinkProgress)
“…[R]enewable energy resources were as important as natural gas in driving down carbon dioxide emissions in the United States over a seven-year period beginning in 2007…U.S. energy-related carbon dioxide emissions dropped roughly 10 percent between 2007 and 2013. Renewables contributed between a fourth and a third of this reduction. Switching from coal to gas in the power sector and changes in energy demand played similar roles in emissions reductions over that period…[After rising steadily from 1990 to 2007, energy-related CO2 emissions started a sharp turn downward in 2207] and, by 2013, annual CO2 emissions had decreased by 10 percent. Over this same period, total renewable energy capacity increased significantly in the United States [according to Factoring in the Forgotten Role of Renewables in CO2 Emission Trends Using Decomposition Analysis, which affirms the findings of] a Bloomberg New Energy Finance report, which found that in 2017 renewable energy and energy efficiency were the primary drivers behind a drop in power sector emissions, which helped drive overall U.S. greenhouse gas emissions to their lowest levels since 1991…” click here for more
New Energy Leaped Ahead In 2017 While Old Energy Dropped Defying EIA's Earlier Forecasts For 2017, Electricity From Renewable Sources Increased By 13.2% While Coal, Gas, Oil, And Nuclear Power All Declined
Ken Bossong, February 28, 2018 (Sun Day)
“…[An analysis of U.S. Energy Information Administration (EIA) data showed] electricity generated by renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) was 13.2% higher in 2017 (Table 7d) than in 2016…[And] the production by each renewable energy source - as well as its share of the total energy mix -increased: solar (utility-scale + small-scale) was up by 40.5%, hydropower by 12.0%, wind by 12.0%, biomass by 2.1%, and geothermal by 0.9%...Combined, renewables accounted for 17.6% of total electrical generation in 2017, compared to 15.3% in 2016. Wind topped 6% of total electrical generation (6.3%) versus 5.5% a year earlier, while solar reached almost 2% (1.9%) compared to 1.3% in 2016. Solar has now moved into third place among renewables, ahead of biomass and geothermal. Taken together, non-hydro renewables (inc. distributed solar) grew by 14.1% and topped 10% of U.S. electrical generation in 2017 (10.2%) compared to 8.8% in 2016...In contrast, the electrical output by coal, natural gas, oil, and nuclear power all declined…” click here for more
