29% Growth in Wind Power during 2008

- Adam Clare 1 Comment

The Worldwatch Institute has completed a study of wind power in 2008 and concluded that wind power generation increased by 29%!

Europe now generates 65,946 MW of wind power, or 55 percent of global capacity.

Germany still leads the region, generating 23,903 MW of wind power, but it saw new installations drop slightly in 2008.

In Asia, China ranked second globally in new capacity last year, adding some 6,300 MW to bring its total to over 12,200 MW.

The Chinese government has now surpassed its 2010 goal of 10,000 megawatts of installed wind power and a senior energy official said in April the country will have 100,000 MW in place by 2020.

Sustainable Energy – without the hot air

- Adam Clare 1 Comment

There is a lot of information out there on how we’re destroying our planet and there’s tons of information about how we can save it (this site looks at saving it). David J.C. MacKay has written a book Sustainable Energy – without the hot air that takes all the climate change information and creates an analysis that is much easier to understand than most writing on the subject. The best part is that you can read the entire book for free.

From the introduction to the synopsis:

We have an addiction to fossil fuels, and it’s not sustainable. The devel-
oped world gets 80% of its energy from fossil fuels; Britain, 90%. And
this is unsustainable for three reasons. First, easily-accessible fossil fu-
els will at some point run out, so we’ll eventually have to get our energy
from someplace else. Second, burning fossil fuels is having a measurable
and very-probably dangerous effect on the climate. Avoiding dangerous
climate change motivates an immediate change from our current use of
fossil fuels. Third, even if we don’t care about climate change, a drastic
reduction in Britain’s fossil fuel consumption would seem a wise move if
we care about security of supply: continued rapid use of the North Sea Photo by Terry Cavner.
oil and gas reserves will otherwise soon force fossil-addicted Britain to de-
pend on imports from untrustworthy foreigners. (I hope you can hear my
tongue in my cheek.)

How can we get off our fossil fuel addiction?

There’s no shortage of advice on how to “make a difference,” but the
public is confused, uncertain whether these schemes are fixes or figleaves.
People are rightly suspicious when companies tell us that buying their
“green” product means we’ve “done our bit.” They are equally uneasy
about national energy strategy. Are “decentralization” and “combined
heat and power,” green enough, for example? The government would have
us think so. But would these technologies really discharge Britain’s duties
regarding climate change? Are windfarms “merely a gesture to prove our
leaders’ environmental credentials”? Is nuclear power essential?
We need a plan that adds up. The good news is that such plans can be
made. The bad news is that implementing them will not be easy.

Using Kites for Wind Energy

This TED Talk is about inventor Saul Griffith’s idea to use giant kite wind turbines to create energy. Watch it now:

Radiant Heat Flooring for Warm Feet

- Adam Clare 1 Comment

Radiant heating is so great that it seems that it’s too great for us to have in every home. Essentially, it’s a system to heat your house using heating tubes under the floor. Here’s a blog post on the coolness of a hot floor.

Perhaps the most appealing aspect of the radiant floor heating is that it creates not just a warm room, but an entire warm floor. The heat still rises, but it’s rising uniformly from ground zero instead of from a single fixture or a couple of vents. The result is often that rare anomaly, barefoot comfort in the dead of winter. Such systems are particularly good for homes with high ceilings, where forced-air heat often ends up where it is least needed unless the homeowner is endowed with the agility of a bat.
Not only are radiant-heat floors warm, but the system does without unsightly and space-hogging ductwork in the home. Lacking vents to keep uncovered, you can place your furniture and doodads wherever. There’s no blasting faux-desert wind wreaking havoc on the hairdo. The system is silent, and in this noise-prone day and age, that is golden. It also works well with tile and wood floors, in addition to concrete.
Not only does the home look nicer, but so do the energy bills. Because of the even heating generated by a radiant floor heating system, its thermostat may be set 2-4 degrees lower than that of a forced-air heating system. This in turn can reduce energy costs by 10-40%. (Check with your local utility company to get an estimate of how much a 2-4 degree decrease would save you).

This is Reality

- Adam Clare 1 Comment

This is Reality is project that is designed to counter the coal industry’s claim that clean coal is, well clean. Awareness projects like this are badly needed when there are multimillion dollar campaigns trying to convince people that burning a finite resource is good for the environment.

Today, coal power plants emit carbon dioxide (CO2), the pollutant causing the climate crisis. A third of the America’s carbon pollution now comes from about 600 coal-fired power plants. And of the more than 70 proposed new coal power plants, barely a handful have plans to capture and store their CO2 emissions. If these dirty plants are allowed to be built, this will mean an additional 200 million tons of global warming pollution will be emitted in America each year. Until coal power plants no longer release CO2 to the atmosphere, coal will remain a major contributor to the climate crisis.

Scientists indicate that we can avoid the worst climate impacts if we turn CO2 emissions around in the next few years. The Chairman of the Intergovernmental Panel on Climate Change (IPCC), Dr. Rajendra Pachauri, in 2007, said, “If there’s no action before 2012, that’s too late. What we do in the next two to three years will determine our future. This is the defining moment.” For coal to maintain a role in America’s energy mix, the industry must act quickly to stop emitting CO2.
