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.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

In addition to its regional and temporal scope, this study is distinct from earlier LCA literature in four key aspects: This study considers the lifetime average carbon intensity of the fuel and electricity mixes, including biofuels and biogas. This is especially important for assessing the GHG emissions of PHEVs.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

A study by Mark Z. Even if you have 100 percent capture from the capture equipment, it is still worse, from a social cost perspective, than replacing a coal or gas plant with a wind farm because carbon capture never reduces air pollution and always has a capture equipment cost.

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. Gt C (15 Gt CO 2 ) per year, according to the study.

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.

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.
