Berkeley study finds renewable portfolio standards insufficient to meet 2030 GHG emission targets; new policy required

Green Car Congress

The least expensive way for the Western US to reduce greenhouse gas emissions enough to help prevent the worst consequences of global warming is to replace coal with renewable and other sources of energy that may include nuclear power, according to a new study by University of California, Berkeley, researchers.

Royal Academy of Engineering Report Says EV Success Depends on Low-Carbon Electricity, Universal Broadband Provision and Smart Grids

Green Car Congress

The introduction of electric vehicles on a large scale in the UK can only have a beneficial effect on CO 2 emissions if low-carbon electricity, universal broadband provision and smart grids are in place to support the transition, according to a new report published by the UK Royal Academy of Engineering.

MIT researchers propose subsea version of pumped hydro for renewable energy storage

Green Car Congress

The 1,000 wind turbines that the spheres could anchor could, on average, replace a conventional on-shore coal or nuclear plant. Preliminary estimates indicate that one such sphere could be built and deployed at a cost of about $12 million, Hodder says, with costs gradually coming down with experience.

Georgia Tech study finds MD electric urban delivery trucks have cost advantages over diesel in some conditions; relative benefits depend on numerous factors

Green Car Congress

Researchers at Georgia Tech have compared medium-duty (MD) electric and diesel urban delivery trucks in terms of life-cycle energy consumption, greenhouse gas (GHG) emissions, and total cost of ownership (TCO). One surprise among their findings was that the electric truck had cost advantages over the diesel vehicle under some conditions.
