Last week, IKEA announced plans to install solar energy panels on five locations in the Midwest, extending the company’s solar presence to nearly 85 percent of its US locations. Pending governmental permits, installation can begin this winter, with completion expected in summer 2012.

Collectively, the five stores will total approximately 20,400 panels, 4.8 megawatts (MW) of solar generating capacity and an annual output of 5.62 million kilowatt hours (kWh) of electricity –that’s the equivalent to reducing 4,273 tons of carbon dioxide (CO₂) and  equal to eliminating the emissions of 760 cars or providing electricity for 484 homes yearly (calculating clean energy equivalents at www.epa.gov/cleanenergy/energy-resources/calculator.html).

This investment by IKEA reinforces the company’s long-term commitment to sustainability and confidence in photovoltaic (PV) technology, and it’s worth noting that IKEA will own and operate each of its solar PV energy systems atop its buildings, as opposed to a solar lease or PPA (power purchase agreement).

If you’re curious about more details, here are a few of the locations, along with approximate system statistics and corresponding clean energy equivalents: (more…)

PepsiCo’s Frito-Lay North America division announced last week that its Casa Grande, Arizona, manufacturing facility has reached “near net zero.”

The company’s “near net zero” vision was to transform an existing facility so that it would be as far off the grid as possible, running primarily on renewable energy sources and recycled water, while producing nearly zero landfill waste.

In order to achieve this goal, Frito-Lay invested in and implemented a combination of technologies.

For instance, the Casa Grande facility now generates two-thirds of all energy used from renewable sources.  For example, five separate and distinct solar photovoltaic (PV) systems, installed throughout the property, produce nearly 10 million kilowatt-hours (KWHs) of electrical power. (Two solar fields of single axis tracking PV systems with more than 18,000 solar panels were installed on 36 acres of the facility’s agriculture property. The three additional PV fields include a dual axis tracking system, a single axis covered parking lot and 10 sterling engine dual axis tracking systems.)

In addition, the company is working toward: (more…)

Walmart plans to install solar panels on up to 60 more stores in California –which means the company will be generating solar energy at more than 75 percent of its stores in the state.

When complete, Walmart’s total solar commitment in California is expected to:

• Generate up to 70 million kilowatt hours of clean, renewable energy per year, which is the equivalent of powering more than 5,400 homes (using the EPA calculator).
• Avoid producing more than 21,700 metric tons of carbon dioxide emissions per year, which is the equivalent of taking approximately 4,100 cars off the road (using the EPA calculator).
• Provide 20 to 30 percent of each facility’s total electric needs.
• Total more than 130 stores by the end of 2013.
• Make California the first state in the US where Walmart has devoted this level of commitment to renewable energy. (more…)

For the first time ever, Google has released information about its carbon footprint.

Last week, the company revealed that in 2010 it generated a total of 1.46 million metric tons of carbon dioxide. As The Guardian points out, those emissions are slightly higher than the country of Laos in south-east Asia and about equivalent to the UN’s operational footprint.

However, Google says its ultimate carbon impact is zero –because the company: (more…)

Oil prices were volatile again last week, topping off at about $100 a barrel, and now there’s another new wrinkle that has traders and analysts scratching their heads: futures contracts for light, sweet crude and Brent crude differ by nearly $20 –an unprecedented gap for these contracts, which typically trade within $1 of each other.

Naturally, as consumers, we’re all feeling the pinch of rising gas prices every time we fill up at the pump.

But, what about the ripple effect of $100/barrel gasoline? How much do rising gas prices—and the tremendous volatility in the oil markets –affect everything else we buy?

As Michael Koploy rightly points out at his recent blog post, Gas Stats: How Rising Fuel Prices Affect Logistics, soaring energy prices impact other commodities, such as minerals, food, and consumer goods –even though this effect doesn’t typically get the press it deserves.

Koploy illustrates the direct correlation between the rise in energy prices and the (sometimes dramatic) increases in commodity prices with this infographic, revealing the trickle-down effect of rising gas prices, January 2010 vs. January 2011: (more…)
