The Price of Oil

- Adam Clare

The increasing price of oil is having a positive impact on the environment, and it looks like this trend will continue. Energy analysts are saying that the sheer economic cost of oil is forcing people to look into alternative energy sources. Yeah!

Record U.S. crude oil futures near $124 a barrel have reached a “break point” that will spur a shift away from an oil-centric transportation sector toward alternatives, energy analyst Daniel Yergin said on Wednesday.

Yergin, chairman of Cambridge Energy Research Associates, told Reuters that U.S. crude oil prices — which hit a record $123.93 a barrel on Wednesday — will hasten the adoption of cellulosic biofuels made from switchgrass and woodchips, as well as battery-powered cars and fuels derived from coal.
…
Yergin countered the notion that global demand for gasoline, jet fuel and other transportation fuels is chiseled in stone because drivers have few current alternatives.

One Town 100% Wind Powered

- Adam Clare

A small town in America has switched to using 100% wind power for all their energy needs.

“What’s interesting is my husband is in the oil business but that’s alright, we’re thrilled to have wind energy here. As Americans we need to get more independent,” Rock Port resident Kim Bunton said.
“It’s a big deal,” Project Director Eric Chamberlain said. “It’s a big deal for renewable energy and it’s a big deal to be energy independent.”

Chamberlain was born and raised in Rock Port.

“What we’re celebrating is that the wind farm in Rock Port can produce more energy each year than what this community uses, and that has never been done before,” Chamberlain said.

And that’s why everyone showed up. From the celebration and speeches downtown to the city’s power plant, the guy who made it all happen explained what it is all about.

“What we’re showing here is the city is producing 2 megawatts more than they need, so in essence, this meter is running backwards,” Chamberlain said.

Use Solar Power During the Night

Storing energy in batteries is expensive, not the best thing to the environment, and inefficient when used on a large scale. The inability to store solar energy over the long-term has been a problem for hte adoption of solar power generation. That is, until now. THe New York Times is reporting on some companies that have found ways to store the energy solar power plants use in a giant thermos.

At Black & Veatch, a builder of power plants, Larry Stoddard, the manager of renewable energy consulting, said that with a molten salt design, “your turbine is totally buffered from the vagaries of the sun.” By contrast, “if I’ve got a 50 megawatt photovoltaic plant, covering 300 acres or so, and a large cloud comes over, I lose 50 megawatts in something like 100 to 120 seconds,” he said, adding, “That strikes fear into the hearts of utility dispatchers.”

Thermal storage using molten salt can work in a system like Ausra’s, with miles of piping, but if the salt is spread out through a serpentine pipe, rather than held in a heavily insulated tank, it has to be kept warm at night so it does not solidify, among other complications.

A tower design could also allow for operation at higher latitudes or places with less sun. Designers could simply put in bigger fields of mirrors, proponents say. A small start-up, eSolar, is pursuing that design, backed by Google, which has announced a program to try to make renewable electricity for less than the price of coal-fired power

Free Flowing Hydro Power

- Adam Clare

TreeHugger has a post up that serves as a good reminder of all the tidal power generators that are being built in North America right now. Including Ontario’s announced tidal wave power feasibility study.

The Cornwall Ontario River Energy Project – 15 Megawatts
The province of Ontario is investing C$2.2 million into a project to demonstrate the feasibility and commercial viability of using free flow turbines to harness some of the St. Lawrence River’s kinetic energy and turn it into electricity.

This project is for 15 megawatts, enough to power 11,000 average-sized homes, but Verdant estimates that “there is enough potential power in the water currents of Canada’s tides, rivers and manmade channels to generate 15,000 MW of electricity using its technology”. That would be about the equivalent of 15 big coal power plants.

But we have to wonder… Did they pick Cornwall just because they could make a really cool acronym? The Cornwall Ontario River Energy (CORE) Project.

Put Your Fridge Outside

- Adam Clare

I’ve always found it fascinating that in Canada we don’t have a system in our houses that use the naturally cold air outside (during the winter of course) to cool our fridges. I’m not the only one who has wondered this.

World Changing has wondered this as well:

“…designed to provide such free cooling for walk-in coolers, freezers and cold storage warehouses. The system utilizes an electronic controller to finely tune the operation of standard refrigeration equipment, and this controller simply monitors the outdoor temperature and desired temperature settings and stops refrigerator evaporator fans when not needed, which also reduces the compressor’s refrigeration load. Proper airflow is maintained when the evaporator fans switch off by operating one or more energy-efficient circulating fans.”
