Tidal Energy: An Overview Tides are caused through a combination of forces created by the gravitational pull of the sun and the moon and the rotation of the earth. Energy naturally present in water bodies – or in their movement – can be used for generation of electricity, through tidal, wave and thermal energy. Energy [...]

Note the market for water heaters in India is around $200 million annually and solar water heaters have managed to capture more than 30% of the market showing that solar water heaters are now a part of the mainstream. Note many solar products are starting to become more mainstream as their price competitiveness increases every year. Solar Panels which are the most widely used solar product has seen the price come down by almost 80% in the last few years .

Concept A smart grid is an electrical grid, that is digitally enabled to procure & distribute information in order to improve the efficiency, reliability and sustainability of electrical devices. It involves the application of digital processing and communications to the power grid. A smart grid replaces analog mechanical meters with digital meters that record usage in [...]

The Indian Solar Power Industry is starting to see some Solar M&A activity pick up as the sector starts maturing. The Indian Solar Energy Industry starting picking up pace in 2009 with the advent of the first phase of the solar federal subsidy which envisaged putting up 20 GW by 2022 (a figure which I think is too low btw) . A large number of companies entered the fray many of which were small . These companies hoped to profit from selling the licenses rather than being serious players. Many of these companies could not do so as the reverse auction process was quite competitive. A large number of companies also got started to take advantage of individual state subsidies from governments in Gujarat.

Solar Energy is one of the best ways to bring energy to the disenfranchised poor in Africa and Asia which have no access to electricity and energy. Note Solar Panel prices have fallen by almost 90% in the last 4-5 years making solar energy much more accessible to the poor . Solar Panels can be now be bought at less than $200 which makes them affordable to large sections of the poor. They having stopped costing a ton in subsidy money given the low prices. Besides massive capacities exist in China and other places in Asia which can churn out solar panels in the hundreds of millions.

Renewable Energy Industry is going through some of the toughest times yet with profits and share prices of Green Companies crashing. 2011 was a horrendous year with the biggest solar company by value First Solar being the worst performer in S&P 500. Many of the biggest wind and solar companies were mired in red ink as competition and oversupply from China led to green indicies falling by more than 50% . Many of the biggest companies collapsed and many others are on lifeline.
