Report finds says “negative emissions technologies” need to play a large role in mitigating climate change

Green Car Congress

To achieve goals for climate and economic growth, “negative emissions technologies” (NETs) that remove and sequester carbon dioxide from the air will need to play a significant role in mitigating climate change, according to a new report from the National Academies of Sciences, Engineering, and Medicine.

Perspective: Despite Solyndra’s death, the future of solar energy is sunny

Green Car Congress

With subsidies long in place for nuclear, coal and gas in the US along with the cheap cost of production for coal and natural gas, solar is essentially competing with that $0.10/kWh kWh average cost of electricity in the United States and globally.

EPA researchers suggest US electricity consumers should be willing to pay 2-4x for emission-free alternatives to fossil fuel electricity due to health impacts

Green Car Congress

kWh—approximately 2–4 times current retail costs—for emission-free alternatives to fossil fuel electricity due to the cost of health impacts from fossil fuel electricity, according to a new analysis by a pair of researchers at the US Environmental Protection Agency (EPA) Clean Energy and Climate Change Office, Region 9.

IEA: governments must act to ensure sufficient supply of critical minerals to meet net-zero goals

Green Car Congress

Not only is this a massive increase in absolute terms, but as the costs of technologies fall, mineral inputs will account for an increasingly important part of the value of key components, making their overall costs more vulnerable to potential mineral price swings.

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

Green Car Congress

They also found that abundant natural gas can, however, help reduce the costs of achieving GHG reduction goals. Shale gas in particular has grown rapidly, from less than one percent of US production in 2000 to 34% in 2012, and projections show strong production growth continuing for the foreseeable future.

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.

Researchers develop microwave-driven, energy-efficient process for magnesium production

Green Car Congress

The hot reaction zone is either gas-fired, coal-fired, or electrically heated in a furnace; the condensing section is water-cooled. The cost of producing Chinese-Pidgeon magnesium is $2.50/kg. The US Magnesium LLC cost, using a more environmentally sound approach, is approximately $3.31/kg.). kWh/kg and has emissions of 6.9
