In this post, which is part of a series of posts on the hot button topic of rising gas prices and record oil company profits, Robert argues against the powerful temptation to tax Exxon/Mobile’s recent windfall profits. Doing so will do nothing to lower recent high gasoline prices, which in reality are driven by global supply and demand and will risk driving more of the oil business overseas. He goes into some depth on each of the main tax breaks and subsidies that the oil sector now enjoys and argues the case that these need to be continued and that the oil sector should not be singled out. He poses the question if it is fair for ExxonMobil to pay even more income taxes, than why not Apple or Google, which have much higher profit margins?
In this post Julius discusses some of the innovations that are cropping up in forward thinking data center design ranging from the adoption of Yahoo’s chicken coop architecture that is suited for utilizing ambient air cooling; new server designs optimized for hot aisle/cold aisle architecture; and innovative approaches to power supply. While most operators do not have the deep pockets and resources of players like Facebook, Google, Yahoo or Amazon — all mentioned in this post — the kinds of forward thinking innovations being pioneered by these companies are bound to have a wider impact.
This post looks at a real world case, the Gai Building in Orlando Florida that was built to LEED Silver standards and uses this to talk about some of the reasons the developer chose to go with the LEED Silver standard. It uses this example to address some of the advantages of building green and a few of the shortcomings of the LEED certification standards. It makes the case that only when a developer can determine that a proposed sustainable project is economically viable and will give the developer a definable market advantage will these projects get built in practice.
In this post, Dallas writes about bio natural gas a potentially disruptive renewable energy technology that may be poised to expand out of the niche markets it has so far been constrained in. After describing what bio natural gas is and is not, the post delves into some of the specifics for why this sector may be ready to take off, and why it has a big upside potential. The study, which this post summarizes suggests that bio natural gas may emerge as the lowest cost renewable power in the future, once available at scale.
Concentrated solar photovoltaic energy or CPV is a relative newcomer to the solar power arena and is showing signs of entering into a phase of very rapid growth. It works by concentrating the sun onto a small area of active PV, which operates at around twice the efficiency of normal PV, and promises savings because it requires only a fraction of the photovoltaic material that normal systems require. The DOE has announced a $90 million loan guarantee to support a planned 30-megawatt facility near Alamosa, Colorado.
Wind farms up here in the Pacific Northwest may soon be shut down temporarily because there is no transmission capacity to move this green renewable power to where it is needed. A record snowfall in the mountains at the headwaters of the Columbia river system is about to begin melting and will send a surge of water down the river. Because this water cannot be sent over the spill ways without endangering already endangered Salmon and Steelhead fish it needs to be run through the turbines. There is just too much power for the regional markets and the existing transmission infrastructure to handle and thus wind farms are likely to be idled. What this exposes is the need for an improved Ultra high voltage long distance electric transmission network that is capable of moving surplus power from one region to another.
This post reports on a recent survey that indicates that the green roof sector in the US and Canada is enjoying excellent growth in spite of the very difficult economic environment that is prevailing in the building sector in general. The survey reports a growth of 28.5% and provides some background on what types of buildings and what cities are leading the adoption of green roofs.
This post addresses some of the misdirections being propagated by politicians about the rising price of gasoline and points at the actual underlying reasons for these rising prices, clearly illustrating how the global price of crude oil is by far the largest factor in the price of a gallon of gas at the pump and that fuel taxes are a small portion of the overall price. It goes on to make the point that these taxes are also badly needed by a rapidly crumbling national road infrastructure. This is a complex subject; this article provides an important perspective on it.
This post showcases the Impulse, a really cool solar powered car built by the CalSol student group of UC Berkeley and that has been entered to compete in the World Solar Challenge. Hats off to these young engineers and designers for putting together such a sleek racer that showcases the power of the sun and lightweight vehicle construction. Events such as these are also an important way to raise awareness of the potential of renewable energy.
