Chances are that you’ve visited the
website google.com. Google is
not only a leader in online tech, but
it’s also investing in high-tech
alternative energy, especially different
kinds of solar power. Lester Graham
talked with Google’s Green Energy
Czar – yes, that’s his real title – Bill
Weihl. His job is not only
to make Google more energy efficient,
but to investigate and invest in new,
cleaner energy use and generation:

Lester Graham: Last year, a report indicated performing two Google searches from a desktop computer could generate about the same amount of carbon dioxide as boiling a kettle for a cup of tea. How true is that?

Bill Weihl: We think, as, in fact, does the scientist who was behind most of the data there, that that report was actually off – that you, in fact, could do several hundred Google searches, if not more, for the emissions that are involved in boiling enough water to make a cup of tea.

Graham: What is Google doing to reduce energy consumption, or, at least, reduce greenhouse gas emissions?

Weihl: We have cut our energy consumption in our data centers – data centers are the, you know, big facilities that contain lots and lots of servers. We have cut the energy usage in those facilities by over 50%.

Graham: Is there anything we can do so that when we do use Google we’re being as energy efficient as possible?

Weihl: If you’re buying a new computer, look for one that’s energy efficient. And in the US that means look for one, at a minimum, that’s Energy Star compliant. Laptops also tend to be more energy efficient than desktops, in part because just to make the battery last long enough to be useful, they have to work really hard in designing them to make them energy efficient. The second thing you can do is when you’re not using your system, when it’s sitting there idle, you can set it so that it will go to sleep automatically, or manually, if for some reason it doesn’t go to sleep automatically, you can very easily tell it to go to sleep. That’s much more convenient, obviously, that shutting it down, having to reboot, and restart everything. And it uses about the same energy in stand-by mode as it does when it’s off – which is, in the order of 1 to 5 watts, far less than it uses when it’s just sitting there idle with the screen on and doing nothing.

Graham: Let’s look beyond the world of computers. Google has invested in research for energy efficiency in cars and electric generation. You have a program that’s called ‘R.E. is less than C’ or ‘renewable energy for less than the cost of coal.’ That’s ambitious. Is it realistic?

Weihl: First of all, it’s hugely ambitious. Secondly, I believe it is realistic. And third, I think it’s absolutely necessary. Today, coal is, by far, the cheapest form of energy, or electrical energy, that we consume, except perhaps for hydroelectric power, which is comparable in cost. But at least in this country, and most of the developed world, we’re not going to be building large amounts of new hydroelectric generating capacity. We’ve already dammed most of the rivers that are worth damming. We are, however, still building new coal plants. And coal is not only very cheap, but also it is, by far, the dirtiest, in terms of greenhouse gas emissions, of any of the sources of energy that we use. So I think it is necessary, in terms of dealing with the climate crisis that we are facing, to find a way to, over time, replace coal with cleaner sources of energy. And the only way, as a society, I think that we’re going to do that is if it makes economic sense. So that’s why we really started to focus on this initiative we call ‘R.E. less than C’ – to really try to drive innovation as rapidly as possible on the technology for generating renewable power to try to drive its cost down very quickly.

Graham: Bill Weihl is the Green Energy Czar for Google. Thanks very much for your time, I appreciate it.

Weihl: My pleasure. Thank you.

Farmland Increasing Worldwide

The amount of farmland is decreasing throughout the Midwest. But scientists say the amount of agricultural land is increasing worldwide… bringing additional challenges to U.S. farmers. The Great Lakes Radio Consortium’s Chuck Quirmbach reports:

Farmland is disappearing throughout the Midwest, but scientists
say the amount of agricultural land is increasing worldwide… bringing
additional challenges to U.S. farmers. The Great Lakes Radio
Consortium’s Chuck Quirmbach reports:


Researchers have used satellite data and statistics from
government agencies to determine that more than one-third of the
earth’s land is used for agricultural activity.


Scientist Navin Ramankutty is at the University of Wisconsin-Madison.
He says urban sprawl may be gobbling up farmland in the Midwest,
but in places like South America, farms are replacing the rainforest.
Ramankutty says the change concerns U.S. soybean farmers.


“The U.S. still continues to be the largest soybean exporter in the world,
but Brazil’s catching up really fast. So, soybean farmers here in the
Midwest are concerned about whether/how their markets will change
in the future.”


But while the global growth in agriculture is feeding more people,
Ramankutty says there are downsides for the environment in terms of
more water pollution and loss of forests. So, he says his research
team is trying to weigh the tradeoffs, and make recommendations on
what might be the best locations for new farms.

Dire Warnings From Worldwide Frog Study

The most comprehensive study of amphibians ever done shows nearly a third of species
are theatened with extinction. The Great Lakes Radio Consortium’s Erin Toner reports:


More than five hundred scientists from more than sixty nations were involved in the
recent Global Amphibian Assessment. The three-year study looked at the status of more
than 5700 known species of frogs, toads, caecilians, and salamaders. It found out that
more than thirty percent of them are near extinction. In the Americas and Australia,
outbreaks of a highly infectious fungal disease have hurt amphibian populations.


But worldwide, the report says the biggest factors for the decline are habitat destruction
and pollution. It also says since amphibians depend on freshwater to survive, the loss
of species shows the Earth’s freshwater supply is in danger. But scientists say the
negative trend could reverse with a swift commitment of resources, such as creating new
protective areas and captive breeding grounds, and better protection of fresh water.
