Study finds climate impact of hydropower varies widely

Green Car Congress

Although hydropower is broadly considered to be much more environmentally friendly than electricity generated from fossil fuels (e.g., Although hydropower is broadly considered to be much more environmentally friendly than electricity generated from fossil fuels (e.g., They also estimated emissions caused by flooding the reservoir.

EEA report: EVs are better for climate and air quality

Green Car Congress

Battery electric cars emit less greenhouse gases and air pollutants over their entire life cycle than petrol and diesel cars, according to a European Environment Agency (EEA) report. Emissions are usually higher in the production phase of electric cars, but these are more than offset by lower emissions in the use phase over time.

The top graph depicts CTL in a no policy scenario; the bottom graph, for CTL in a world climate policy scenario. However, the viability of CTL becomes quite limited in regions with climate policy due to the high conversion cost and huge carbon footprint. of global electricity demand.

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. In the journal Joule , Harvard researchers report the most accurate modelling yet of how increasing wind power would affect climate.

Study Concludes Peak Coal Will Occur Close to 2011

Green Car Congress

A multi-Hubbert analysis of coal production by Tadeusz Patzek at The University of Texas at Austin and Gregory Croft at the University of California, Berkeley concludes that the global peak of coal production from existing coalfields will occur close to the year 2011. The CO 2 emissions from burning this coal will also decline by 50%.

Study concludes abundant shale gas is neither climate hero nor villain; need for targeted GHG reduction policy

Green Car Congress

While natural gas can reduce greenhouse emissions when it is substituted for higher-emission energy sources, abundant shale gas is not likely to substantially alter total emissions without policies targeted at greenhouse gas reduction, according to a new study by two researchers at Duke University. —Newell and Raimi.

BNEF, Snam, IGU report finds global gas industry set to resume growth post-pandemic; low-carbon technologies for long-term growth

Green Car Congress

After growing by more than 2% in 2019, global gas use is set to fall by around 4% in 2020, as the COVID-19 pandemic reduces energy consumption across the global economies. The report shows that medium-term growth will come from increasing cost-competitiveness and increased global access to gas. Low-carbon gas.
