This new Tesla battery will power your home, and maybe the electric grid too
“Like many of Tesla’s projects, this one is coming up fast. Mastermind electric power guy Elon Musk announced in an investor call that the designs for the home battery are complete. The public could get a glimpse of the design within the next month or two, with production beginning in as little as six months.
Tesla’s new stationary battery could be the gateway that finally links renewable energy to everyday consumers in a way that makes sense. The challenge of storing clean energy from solar or wind is one of the reasons people are sticking with grid power. Although Musk hasn’t commented on the cost of Tesla’s newest energy offering, chances are good that it will still represent a savings versus grid electricity over the course of its lifetime.”
The competitiveness of renewable power generation technologies continued improving in 2013 and 2014, reaching historic levels. Biomass for power, hydropower, geothermal and onshore wind can all provide electricity competitively against fossil fuel-fired power generation. Solar photovoltaic (PV) power has also become increasingly competitive, with its levelised cost of electricity (LCOE) at utility scale falling by half in four years.
Renewable Power Generation Costs in 2014 aims to reduce uncertainty about the true costs of renewable power generation technologies, so that governments can be more ambitious and efficient in their policy support for renewables. As this comprehensive report from the International Renewable Energy Agency (IRENA) underlines, perceptions that such technologies are expensive or uncompetitive are outdated, at best.
