Today the world is going mobile -Even Laptops are old fashioned now . The era of ipads, smart mobiles is already here. Every one wants the world in their hands  . But their is one hiccup with this gizmos, the battery. The prime power driver for these mobile devices is the major hurdle in being completely mobile - you have to wire often to get it charged. Lithium ion is the present power source for most of the Laptops and gadgets. Battery is one place where to say frankly innovation is slower. 

Now Oxford University is developing a new technology using catalysts which make hydrogen from formic acid and could eventually replace lithium batteries and power a host of mobile devices...

To date,Google has invested over $680 million in innovative clean energy companies and projects through Google.org, Google Ventures and Google corporate investments. Google intends to supporte cleantech companies with scalable and potentially breakthrough technologies that could produce renewable energy cheaper than coal.  Some of the google's investments in clean energy - 

Today Google announced a $280 million investment to create a fund, in partnership with SolarCity, to help the company finance more solar installations across US.This is Google's first investment in "distributed" renewable energy (generated and used right at home). The investment is expected to be a  quadruple-win for Google, SolarCity, the environment, and new customers who get access to clean energy at a economic rates.

Natural gas is important in many sectors of the economy: for generating electricity, as a heat source for industry and buildings, and in chemical feedstock. Despite its vital importance to the economy, natural gas has often been overlooked, or at best taken for granted, in the debate about the future of energy.

Over the past two or three years, this has started to change, and natural gas is finding its place at the heart of the energy discussion. Given the abundance of natural gas available through extensive global resources and the recent emergence of substantial unconventional supplies in the United States and discovery of new sources in some countries, worldwide usage of the fuel is likely to continue to grow considerably and contribute to significant reductions of greenhouse gas emissions for decades to come, according to a comprehensive, multidisciplinary study carried out over the last three years by MIT researchers... 

The estimated half-million garbage pickers in Brazil, known as catadores, turn waste into gold: they sort out recyclable items in the country’s dumps, then sell their findings to recycling companies. The collection of recyclable material in Brazil is largely from these waste pickers. Waste picking activities are supported by government. In Brazil waste picking is now recognized as an occupation . And organized waste pickers are seen as legitimate stakeholders who can voice their opinions at the local, state, and national levels.  But the catadores typically receive only a fraction of the value of the materials they collect because they usually sell to middlemen who earn most of the profits. The process of getting the recyclables to their final destination involves fleets of fuel-consuming vehicles which accounts for one-fifth of their operating expenses.

Now — with help from some MIT students — the catadores have a less-expensive and environmentally friendly fuel option: recycled cooking oil. 

Tirumala Tirupati  temple the abode of Lord Venkateswara is going the greener way . The temple is very famous pilgrimage place of India situated on a hill top (Venkatachalam) in Andhra Pradesh State and is visited on an average by 50,000 pilgrims daily. Given the mammoth number of pilgrims visiting and staying there, power requirement is high. There are many restaurants, cottages , hotels, rest rooms etc.  It is almost like a small city ruled by the Lord . May be due to the power and influence of God or something else the adaption of green technologies is praise worthy on the temple hill unlike the slower tendency for non- conventional sources of energy in the rest of the  country.From gardening to cooking, only non-conventional sources of energy are now being used in the temples of Tirupati.

In a recent blog post Posted by Rick Needham, Green Business Operations Manager of Google, it was declared that Google made first direct investment in a utility-scale renewable energy project — two wind farms that generate 169.5 megawatts of power, enough to power more than 55,000 homes. These wind farms, developed by NextEra Energy Resources, harness power from one of the world’s richest wind resources in the North Dakota plains and use existing transmission capacity to deliver clean energy to the region, reducing the use of fossil fuels. 

After more than five decades of research, a major milestone toward the harnessing of fusion power is expected within the next year or two. This milestone, known as “fusion ignition,” should take place at an experimental facility built for that purpose in California. Known as the National Ignition Facility, or NIF, it started initial experiments last fall.
