Carbon sequestration: Can we bury just the harmful carbon dioxide?

In this first in a series of discussons on carbon sequestration, we meet Marc Hesse, an aspiring graduate student at Stanford, who studies the physical processes that govern the movement of carbon dioxide once injected into the ground. Will it stay down? Will carbon sequestration really help in reducing the harmful effects of increased CO2 concentrations in the atmosphere? Marc makes a start in the debate on this issue.

Stanford’s Green Dorm

A few facts: in the U.S., residential and commercial space accounts for 40 percent of our primary energy consumption and 38 percent of CO2 emissions are from operating buildings. Why, then, is so little attention paid to building energy efficient offices and residences? Prof. Gil Masters from Stanford University wants to change that. His dream to build a student dorm that is green and clean is being realized: the Green Dorm project at Stanford is under way.

Are Carbon Credits Just a Clever Scheme to Make Money? Part II

We continue our discussion on carbon credits with Tom Arnold, chief environmental officer of Terrapass.

Are Carbon Credits Just a Clever Scheme to Make Money?

Meet Tom Arnold, chief environmental officer of Terrapass. The company sells TerraPasses. Buy one and sponsor renewable energy projects such as wind farms, thereby partly or fully counterbalancing your own carbon emissions. How does Terrapass guarantee that their passes indeed lead to carbon emission reductions? Who buys these passes? Is buying a TerraPass an effective way to help reduce global climate change and/or a way to buy off guilt about emitting carbons and a clever ploy to make some money?

Silicon Valley: the epicenter of solar power and clean technologies?

On June 1, Silicon Valley profiled itself as the future epicenter of solar power, energy efficiency and clean technologies at the Energy Summit 2007. Jacob and Desirae, two of my students at Stanford, attended to see with Silicon Valley’s leaders were up to. They report on the conference in this video, so in case you missed it, this is a chance to catch up and listen to what’s cooking and what’s not in the Bay Area.

View From the Top: Shell Oil President John Hofmeister

John Hofmeister, Shell Oil president, sees an important role for his company in supplying the world’s energy in the future. Petroleum (oil and gas) will remain, at least for the near to medium future, the most important energy resource. Shell is also investing, as are many other energy companies, in renewable energy (wind, solar, biofuels) as well as so-called clean coal. Hear John Hofmeister’s views on Shell’s future directions and current energy policies.

Extinguish coal fires and reduce carbon emissions considerably

You may not be aware that coalfires, both natural and man-made, generate large amounts of carbon dioxide. In China alone, the estimated amount equals that of the U.S. transportation sector! Meet Taku Ide, a PhD student at Stanford University, who is on a quest to extinguish these fires.

Alternative Energy Options

Mark Jacobson is a world expert in wind energy and air pollution. He sees wind and solar power — not biomass — as the most optimal energy sources. He says that the increased use of ethanol will not improve the quality of the air we breathe. Mark also strongly believes…

Choosing Renewables: Wind and Solar

Download MP4Alternatives can help create a sustainable energy future. The most promising long-term alternative energy sources are wind and solar: there is plenty of it, greenhouse gas emissions are low, and the required surface area is relatively small — especially when compared to biomass. In this talk, SmartEnergy’s Margot Gerritsen…

Changing the world’s energy systems

download mp4Global warming is happening, and one of the culprits is likely increased emission levels of carbon dioxide and other greenhouse gases as a result of our energy usage. Lynn Orr is director of the Global Climate and Energy Project and one of the world’s leading experts on global warming…
