October 18, 2014 - Think about it. Why would a small island nation that gets 300+ sunny days a year and fairly constant ocean winds import coal, oil, diesel or liquid natural gas to provide power to its citizens?

    Energy storage prices are dropping fast. If you follow me, you’ve seen me write about this before. Energy storage prices have in fact been dropping exponentially for at least 25 years. Here’s a new piece of analysis – a model that uses a 20% learning curve per doubling to that project Li-ion batteries dropping to 5 cents per kwh round-tripped through them by ~2030.

    The carbon capture and storage project at the Boundary Dam in Saskatchewan is about to go live as reported in the press today. The project goal has been to eliminate 90% of the CO2 generated by the coal-fired power plant. Additions have cost $1.4 billion CDN, $115 million over budget, and represent what is believed to be the world's first commercial-scale CCS project to go live.
