Batteries have never been more important. Not only do we all depend on cell phones, tablets and laptop computers that run on batteries, but two enormous industries are in major transitions that rely upon battery technology: personal transportation and the utility industry. The electricity grid is increasingly turning to solar and wind power for generation and both will require effective energy storage if they are to truly become the predominant sources of electricity.
Multiple studies are now reporting that wind and solar power are the cheapest way to make electricity in a growing number of places around the world. A thorough analysis of the levelized cost of energy – which considers every cost component from capital expenditures to operating and maintenance costs over a lifetime – shows that solar and wind power are winning the day.
Germany has continued to be the most aggressive adopter of renewable energy among large industrial nations. The country has the goal of shifting to 100% renewables by 2050. Its continuing embracing of solar and wind generation resources over the past decade has resulted in renewables supplying a third of the country’s power on average.
The city of Holtville in California is sometimes called the “Carrot Capital of the World.” This agricultural community has signed an agreement with Australian company Infratech to build a floating solar power system for its water treatment plant.
