EPIC: state-level renewable electricity mandates increase electricity prices up to 17% over 12 years; cost more expensive than benefit

Green Car Congress

As states take the lead in confronting climate change, a flagship policy is often Renewable Portfolio Standards (RPS). RPS programs, which require that a certain percentage of the state’s electricity come from renewable sources, currently cover 64 percent of the electricity sold in the United States.

New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

The new battery design could help ease integration of renewable energy into the electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. In comparison, the energy density for lithium-ion batteries used in commercial electronics and electric vehicles is around 170–250 Wh/kg.

PNNL study finds that PHEVs and BEVs could serve as feasible resource to offset grid imbalances caused by integration of large amounts of intermittent wind generation

Green Car Congress

The report examined grid conditions in the Northwest Power Pool, which covers Idaho, Montana, Nevada, Oregon, Utah, Washington and Wyoming; many of them home to abundant wind resources and wind energy projects. A comparison between Level 1 and Level 2 charging revealed very little differences. Click to enlarge. traffic.

DOE, BOEMRE and NOAA awarding nearly $5M for projects to advance ocean renewable energy

Green Car Congress

The following awards have been selected to receive funding: Bayesian Integration for Marine Spatial Planning and Renewable Energy Siting. The project team has experience with two such methods that, when integrated, can support the needs of ocean renewable energy planning in the context of coastal and marine spatial planning and beyond.
