You can see lots of attention is focused towards alternative and renewable energy systems. This is due to the soaring energy costs and the need to decrease the climate change effects over earth. Though these solutions may seem complicated for the homeowners in their daily chores, however, the fact is that they are now becoming more accessible to common man. There are number of options available for homeowners which can prove pretty affordable financial investment. Also, by treading these paths, you can benefit from state and federal tax and avail the utility rebates and incentives. The below are the top seven ways which the home owners can heat and power their homes via renewable energy systems.

A reader from the San Francisco Bay Area sent me this article, which he said, “was buried within an article on other SF subjects. Thought you might be interested.”

Green vs. green: San Franciscans’ enthusiasm for going green with “clean energy” in their own homes appears to be about as flat as the economy. (more…)

Each week I receive several emails requesting my advice on career paths within the clean energy space. I thought I’d take a few minutes and jot down a few of the ideas that I normally try to express in response.

First, I congratulate people who want to work in this industry, especially if their interest is rooted in a love of the natural environment and perhaps a sense of duty, or at least a wish, to do something good for mankind and the other 8.7 million species of life forms here on our home planet. But regardless of motive, clean energy is one of few arenas in which there exists a beautiful confluence of the profitable and the philanthropic; we’re helping mankind whether that’s our aim or not.

Here’s a good article on a recently completed solar thermal tower (aka concentrated solar power or CSP) in the desert between Las Vegas and Reno, NV.

The thing to like about solar thermal, as we’ve often discussed here, is that it affords us a fairly low-cost way of storing energy and delivering it when the sun isn’t shining. This is due to the fact that in today’s world, we can store heat energy (in vats of molten salt) far less expensively than we can store electrical energy (in batteries). Thus solar thermal installations can be treated as baseload, delivering power on a consistent 24X7 basis.

That’s the good news. (more…)

Frequent commenter Duke Brooks writes in:

Americans who rail against U.S. polluters should probably spend a few days in the world’s most polluted city, Beijing. What’s good for the goose is good for the gander, as they say. But the lack of outrage from the American left over China’s mass particulate output would tend to expose them for what they are: A political, not ecological, movement.

I don’t think anyone argues that China’s building coal-fired power plants at the rate of one a week is anything other than an abomination; there isn’t too much controversy there — regardless of where one stands politically.  Yet China is the world’s leading investor in renewable energy, and they face a far larger challenge than we do in terms of supplying energy to a skyrocketing number of energy-hungry consumers; it’s one that dwarfs ours here in the U.S.

I don’t know whether you saw this report I wrote a few months back in an attempt to make sense of this paradox: China Is Investing in Renewable Energy — But Why?

For amusement only….

Today I cooked mashed potatoes in my solar oven. The oven is made of one of those shiny windshield shades, a rack from an old countertop oven, a very large clear plastic pretzel container and a 2lb 13oz Prego spagetti sauce jar which I painted black with high temperature paint except for a stripe I left so I could look at what was going on in there. I peeled and cut potatoes to fill the jar and added water and put the arrangement out in the sun around 12:30. About 6:30 I retrieved the arrangement and brought the jar in to see what I had.

Next Saturday I’m doing a book signing at the wonderful Roblar Winery a couple of miles up the road. Though I can’t imagine that I’ll sell more than a dozen books or so, I’m really looking forward to the experience: sipping excellent wine, and talking to people about renewable energy.

Duke Brooks (old friend from school forty years ago) comments on my piece about the Koch brothers’ sponsorship of PBS’s NOVA: “I have heard that the Koch brothers speak very highly of you, by the way.”

Ha! You’re kidding, of course — though I’ve heard that I actually am in fact on the radar screen of big oil – not that that’s a good thing. The other day a guy from South Carolina called me and said, “Craig, your name’s come up twice in the last 24 hours, so I thought I’d give you a call and introduce myself.” He went on to explain, “(One of these incidents) was a conference call among the executive team at Shell Oil.”

“Holy mackerel,” I replied. “I can’t begin to imagine what they were saying about me. I bet it isn’t exactly gushing with praise; I haven’t been too kind to the oil industry.”

Unfortunately, he couldn’t remember what they were saying, or at least claimed he couldn’t. I shudder to think.

Scientists and researchers have been trying hard to find out the power of cloud to harness for everyone’s benefits. They are therefore seen collecting a number of historical data and records to find out how clouds can respond to the earth’s warming. This is critical since clouds are considered to be one the biggest single uncertainty in the attempt to predict the future climate. A few contrarian scientists simply emphasize that cloud will change in such a way that it will basically counterbalance the greenhouse gases released by the mankind. However, a majority or scientists are seen calling global warming a big issue in the coming future. Yet, since past few years, the contrarian scientists or climate skeptics have strong feelings that clouds will save the human race. (more…)

If you were tasked with crafting the worst possible energy policy, what would you do? Well, you’d say, “OK, I’m going to reward bad behavior, and penalize good behavior,” right?  Then you’d send enormous sums of tax-payers’ money to the most egregious polluters you could find, while making sure that any potential competitors were ground into the pavement.   (more…)
