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.

3 Oil Majors That Bet Big On Renewables

Green Car Congress

An analysis of near-term spending plans on renewables by the biggest oil and gas companies shows that real investments in renewable energy will continue to pale in comparison to capex plans for greenfield fossil fuel projects. Good case in point: Italian multinational oil and gas giant Eni S.p.A. 2 Total SA. 2 Total SA.

Global Carbon Project: Global carbon emissions growth slows, but hits record high

Green Car Congress

Driven by rising natural gas and oil consumption, levels of CO 2 are expected to hit 37 billion metric tons this year, according to new estimates from the Global Carbon Project (GCP), an initiative led by Stanford University scientist Rob Jackson. In 2019, consumption of coal is expected to drop 11% in the U.S.—down

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.

Swiss WTW study finds important role for alternative fuels as well as alt drivetrains in move to low-emissions vehicles

Green Car Congress

WTW energy demand and GHG emissions for EV and PHEV drivetrains for various electricity sources; gasoline ICE vehicle is solid square, hybrid the hollow square. First, it considers the performance of both mature and novel hydrogen production processes, multiple electricity generation pathways and several alternative drivetrains.
