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

Green Car Congress

We see $548 billion being invested in battery capacity by 2050, two thirds of that at the grid level and one third installed behind-the-meter by households and businesses. The result will be renewables eating up more and more of the existing market for coal, gas and nuclear. Coal emerges as the biggest loser in the long run.

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 $4.2 million in 2030 (2011$).

They also found that the total costs of ownership (TCO) of the electric and diesel trucks are similar.

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

Green Car Congress

Following the Fukushima disaster in 2011, the Federal government oversaw the immediate closure of eight nuclear plants, with the rest of the stations to be shut down by 2022. However, the financial cost of the shift is causing concern. These costs are primarily borne by consumers. Siemens stands behind the energy transition.

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.

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.

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

The IEA said that this reflects the continued domination of fossil fuels—particularly coal—in the energy mix and the slow uptake of other, lower-carbon supply technologies. Smart grids, for example, make it easier and cheaper to replace fossil-fired power with renewables without jeopardizing the reliability of the energy system.
