China: The World’s Biggest Energy Consumer

China has overtaken the United States to become the world’s largest consumer of energy, according to the International Energy Agency (IEA). The agency reported that in 2009 China consumed 2,252 million metric tons of oil equivalent in the form of crude oil, coal…

Explosion of CO2 Emissions by 2035

If the world’s major nations fail to enact significant changes in energy and climate policies, global carbon dioxide emissions will increase 43 percent by 2035, according to the U.S. Energy Information Agency (EIA). In its annual long-term energy outlook, the EIA projected that global emissions from burning fossil fuels would grow from 29 billion tons [...]

Energy Efficiency Can Eliminate India’s Electricity Shortage

The widespread adoption of energy efficient light bulbs, fans, refrigerators, air conditioners, and irrigation pumps can overcome India’s electricity shortage by 2013 and significantly reduce the country’s rapidly growing carbon dioxide emissions, according to a new report. The study by the Lawrence Berkeley National Laboratory said such simple energy efficiency measures could add $608 billion [...]

Eyeing the Difficult Path To a Sustainable Future

Environmentalist David Orr says the easy part of helping the United States live within its ecological limits may be passing laws, such as one that puts a price on carbon. The hard part, he maintains in an interview with Yale Environment 360, is changing a culture of consumption that causes extensive environmental damage — and [...]

Toward Sustainable Travel: Breaking the Flying Addiction

Flying dwarfs any other individual activity in terms of carbon emissions, yet more and more people are traveling by air. With no quick technological fix on the horizon, what alternatives — from high-speed trains to advanced video conferencing — can cut back the amount we fly?
In most departments I have [...]

Energy Sleuths in Pursuit Of the Truly Green Building

The practice of “commissioning,” in which an engineer monitors the efficiency of a building from its design through its initial operation, just may be the most effective strategy for reducing long-term energy usage, costs, and greenhouse gas emissions from buildings. So why is it so seldom used?
In a different world, [...]

Creation of ‘Synthetic Cell’ Holds Promise for New Types of Biofuels

J. Craig Venter, the genome pioneer, has created a “synthetic cell” by synthesizing a complete bacterial genome and using it to take over a cell. Venter’s breakthrough, reported in the online edition of Science, represents a preliminary step toward the goal of creating microbes from scratch in the lab and [...]
