https://www.theguardian.com/business/2017/may/04/nissan-launches-british-made-home-battery-to-rival-teslas-powerwall Batteries that have powered electric cars around the UK will get a second life providing energy storage for households, with the launch this week of a British-made home battery to rival the one made by Elon Musk’s Tesla. I mentioned Tesla battery a year ago in this blog at  http://www.epanorama.net/newepa/2015/05/02/watch-elon-musk-announce-tesla-energy-in-the-best-tech-keynote-ive-ever-seen-the-verge/ →

http://interestingengineering.com/really-take-run-world-off-renewable-energy/ With electric power establishing itself even further into our modern society, generating it is becoming an even more complex issue. As we seek to find a sustainable power source, we are naturally drawn to the thought of renewable energy. However, the question remains, what would it really take to run the world completely off of →

http://www.edn.com/design/power-management/4458294/Using-a-supercapacitor-for-power-management-and-energy-storage-with-a-small-solar-cell–Part-1 The environment has abundant energy but little power. Energy harvesting can tap the environment’s “infinite” source of energy, and avoids the cost of wiring to mains power or replacing of batteries. This article will look at using small solar cells.  Depending on the light level, whether indoors or out, small solar cells may deliver →

Power-factor correction allows the input current to continuously flow, reduces the peak input current, and reduces the energy loss in the power supply, thus improving its operation →

https://www.forbes.com/sites/jamesconca/2012/06/10/energys-deathprint-a-price-always-paid/#3c839a52709b Everyone’s heard of the carbon footprint of different energy sources, the largest footprint belonging to coal because every kWhr of energy produced emits about 900 grams of CO2. Wind and nuclear have the smallest carbon footprint with only 15 g emitted per kWhr. But how dangerous different energy sources are for people working with →

Innovative Direct-Current Microgrids to Solve India’s Power Woes – IEEE Spectrum article tells that a group at the Indian Institute of Technology (IIT) Madras in conjunction with industrial partners, relies on solar-powered direct-current (DC) microgrids. For homes not connected to the grid, a 125-watt microgrid can serve as the sole source of electricity. For connected →
