Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

This year’s outlook is the first to highlight the significant impact that falling battery costs will have on the electricity mix over the coming decades. The result will be renewables eating up more and more of the existing market for coal, gas and nuclear. trillion of that going to wind and solar and a further $1.5

EIA: US electricity generation from coal and natural gas both increased with summer heat

Green Car Congress

In August 2012, coal produced 39% of US electricity, up from a low of 32% in April 2012, when the natural gas share of generation equaled that of coal. The August coal share of generation is still notably lower than the 50% annual average over the 1990-2010 period. Data for 2011 and 2012 are preliminary. Source: EIA.

Siemens presents three-point plan for implementing cost-efficient energy transition in Germany

Green Car Congress

Relying on a higher share of efficient, low-emission combined cycle power plants and wind energy could save €150 billion (US$200 billion) by 2030 while attaining the same CO 2 targets, Siemens says. However, the financial cost of the shift is causing concern. These costs are primarily borne by consumers. Source: Siemens.

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

Green Car Congress

Researchers at MIT are proposing using a variation on pumped hydroelectric systems for storage of electricity produced by offshore wind farms. The key to this Ocean Renewable Energy Storage (ORES) system is the placement of 30-meter-diameter hollow concrete spheres on the seafloor under the wind turbines. Earlier post.).

What Are Zero Emission Day and National Drive Electric Week?

Blink Charging

There are four guidelines to follow: Refrain from using or burning oil, gas or coal. If an EV is charged with electricity that is generated from renewable sources (such as solar, wind, geothermal, or hydroelectric), then there are no fossil fuel emissions associated with that charging or driving process. per eGallon (US Average).

EPA proposes rule for nationwide 30% cut in GHG from existing power plants by 2030 relative to 2005

Green Car Congress

The value allocated here in EPA’s goal-setting formula was an average heat rate improvement of 6% for coal steam electric generating units (EGUs). The EPA projects that the annual incremental compliance cost of the proposed Option 1 ranges from $5.4 The estimated cost of Option 2 is between $4.2 million in 2030 (2011$).
