Researchers Say Mix of Policies and Current or Near-Term Technologies Could Phase Out US CO2 Emissions from Coal-Fired Power Plants by 2030

Green Car Congress

CO 2 emissions from US coal-fired power plant could be phased out entirely by 2030 using existing technologies or ones that could be commercially competitive with coal within about a decade, according to a paper published online 30 April in the ACS journal Environmental Science & Technology.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

When we turn up the heat in our homes and workplaces, we must balance our personal need for warmth with the global impact of burning fossil fuels like oil, gas, coal, and biomass. The hot air is circulated through a network of pipes inside a sand-filled heat storage vessel. There is nothing special here!” Eronen says, laughing.

University of Calgary Study Finds Large-Scale Adoption of PHEVs in Alberta Could Support Wind Power; PHEV GHG Benefits Range from 40-90% in Emissions Reduction

Green Car Congress

The study found the environmental impacts of PHEVs in Alberta would depend on factors such as vehicle battery size, charging time and wind production levels. Of the installed capacity of just above 12,000 MW, approximately 49% (5,893 MW) is coal fired, 39% (4,686 MW) is gas-fired, 7% (869 MW) is hydro, and 4% (497 MW) is wind powered.

ExxonMobil Outlook: 35% growth in energy demand by 2040; hybrids to account for ~50% of new vehicle sales

Green Car Congress

China will see the largest increase—more than 4 million oil-equivalent barrels per day. As conventional production declines, more of the world’s oil demand will be met by emerging sources that only recently became available in significant quantities: oil sands, tight oil, deepwater, NGLs and biofuels.

BP Energy Outlook 2030 sees emerging economies leading energy growth to 2030; global CO2 emissions from energy well above IEA 450 scenario

Green Car Congress

Between 2010 to 2030 the contribution to energy growth of renewables (solar, wind, geothermal and biofuels) is seen to increase from 5% to 18%. Natural gas is projected to be the fastest growing fossil fuel, and coal and oil are likely to lose market share as all fossil fuels experience lower growth rates.

Stanford, UC Santa Cruz study explores ramifications of demand-driven peak to conventional oil

Green Car Congress

In contrast to arguments that peak conventional oil production is imminent due to physical resource scarcity, a team from Stanford University and UC Santa Cruz has examined the alternative possibility of reduced oil use due to improved efficiency and oil substitution. 2010, to above 140 $/bbl in constant 2010 dollars).

Green Car Congress

Wind, solar and biofuels are expected to be the fastest-growing energy sources, increasing about 6% a year on average through 2040, when they will be approaching 4% of global energy demand. The Outlook for Energy identifies a significant evolution in the trade of oil and other liquids. —Outlook.
