Gone with the wind

Issue Date: Jun 30, 1999
tapping the potential of wind power is no longer difficult or expensive. Technology to harness this natural force is not only improving, but more nations are finding this alternative source of p ower more desirable because it is locally available, cheap to produce and does not dirty the environment. It is no wonder that wind power has already become the world's fastest growing renewable energy source ( see box: Why wind energy) .

IN THE last 100 years of industrialisationindustrial firms have sought to increase their efficiency and profitability through increases in labour productivity. One fallout of this was the replacement of human labour with machines thatin turnhas resulted in heavy natural costs as industries became increasingly energy- and material-intensive. All this has happened partially because materials and energy have been cheap.

Beads that can heat water

Issue Date: Jan 15, 2012
Describe your work We have developed beads containing cheap phase change materials. These Phase Change Materials (PCMs) store energy and release it by changing from solid to liquid and vice-versa. A large number of organic and inorganic PCMs are available in the market. The advantage of the beads is that they have high heat storage capacity in small size.

The world is witnessing an increase in trade disputes in the renewable energy sector. Countries are trying to strengthen their renewable energy base by preferring indigenous products over imports. This is an obvious dampener for countries with good renewable energy equipment manufacturing capabilities and advanced technology. They argue that such policy measures hinder free trade. Their complaints at the World Trade Organization (WTO) are piling up. India is the latest to be in the spotlight.

Daniel Yergin is among the staunchest critics of the peak oil theory. In 1992 he won a Pulitzer for a book that described the resilience of the oil industry. In a recent article he argued that in 2007-2009, “for every barrel of oil produced in the world, 1.6 barrels of new reserves were added”. He returns to his favourite whipping horse in The Quest, Energy Security and the Remaking of the Modern World.

No climate for cleantech

Issue Date: Nov 15, 2011
What is the outlook for developing countries in getting clean energy technologies transferred to them at a reasonable fee? Will intellectual property rights (IPR) over green technology to mitigate the impact of climate change prove to be a tough barrier? Can poor nations hope to compete with the developed world in bringing such technology to the market? A clear idea of the challenges that lie ahead was available in a speech made by a top American official at a recent conference on clean energy policy in the US, points that have a major bearing on the green future of the developing world. Reproduced below are some of the key points enunciated by Acting Secretary of Commerce Rebecca Blank.
