5 of the Best Companies That Use Alternative Energy


solar panel and sun

Alternative energy sources reduce carbon emissions and offer a sustainable solution for power use. By using renewable energies, these companies are helping the country shift away from its dependence on fossil fuels. This is a major environmental movement, and several big names are leading the way.

Intel Corporation: Massive Purchases of Energy Credits
The Intel Corporation has an annual usage of more than three million kilowatt-hours (kWh), 100% of which is sourced from green power resources. Intel uses biogas, biomass, small-hydro, solar, and wind power. It purchases the majority of its power through renewable energy certificates. However, Intel also generates some green power of its own through 18 solar plants with a capacity of about 7,000 kilowatts (kW). Altogether, the company’s use of green energy has the equivalent impact of taking more than 455,000 passenger cars off the road annually.

Kohl’s Department Stores: On-Site Renewable Energy
Kohl’s uses more than 1.5 million kWh annually, but manages to get 105% of its energy from renewable sources. By producing more green energy than it uses, this company is able to actually put excess renewable energy back onto the grid. Kohl’s purchases renewable energy credits that offset 100% of its power usage. On top of that, the company uses solar panels on select stores. These panels can provide up to 40% of the store’s power in 156 locations across 12 states.

Kohl’s also activated wind turbines on two sites. Vertical turbines outside a store in Findlay, Ohio generate approximately 40,000 kWh a year. Horizontal turbines in Corpus Christi, Texas provide 14,000 kWh annually. Wind turbines are an innovative option that are often powered by the same transformers used for more traditional forms of energy, which allows companies like Solomon Corporation to gradually enter the green market with wind turbine projects.

Whole Foods Market: Energy Efficient Stores
Nearly everything about Whole Foods Market is designed to create a greener environment, so it’s no surprise that this company supplies 107% of its energy usage through renewable resources. A recently constructed Whole Foods store in Brooklyn showcases the extreme lengths to which this company goes to create a green environment. The store uses energy-efficient lighting, refrigeration, and heating systems. Solar canopies in the parking lot supply 20% of the store’s energy, and the lot’s street lights are powered by small-scale wind and solar power systems.

Whole Foods has regularly purchased renewable energy credits to offset its power usage since 2006. The company’s trucks are gradually converting to biodiesel fuels as well.

Staples: Hitting Impressively High Goals
Staples has lofty goals when it comes to its green vision. The company aims to offer only sustainable products, recycle 100% of the technology that it sells, and produce zero waste in its operations. Though it hasn’t hit these goals yet, it’s come particularly far in its attempt to maximize renewable energy use. The company gets 106% of its annual power use of more than 630,000,000 kWh from renewable sources.

Not only does Staples buy energy from renewable sources, it has solar panels on the roofs of many stores to provide additional green power. Staples has also partnered with companies that are pioneering sustainable business practices, such as Rainforest Alliance SmartSource, the GreenBlue Sustainable Packaging Coalition, and CarbonFund.

Unilever: Shifting Energy Usage
Unilever, like the other companies on this list, offsets 100% of its energy use through the purchase of renewable energy credits. While this goes a long way toward supporting the use of renewable energy, it doesn’t actually reduce the amount of non-renewable energy that the company uses upfront. Unilever is taking its energy campaign a step further by striving to cut down on the total non-renewable energy that it consumes.

The company reports that by the end of 2013, renewable energy made up 27% of the company’s total upfront energy use. This is a marked improvement over 15.8% from 2008. Unilever’s goal is to get 40% of its energy from renewable sources by 2020.

Consumers who want to support green energy initiatives can do so easily by shopping at retailers who are part of this movement.

Martifer Solar: BIPV – building-integrated photovoltaics


Martifer Solar Mineirao Brazil stadium

Building-integrated photovoltaics (BIPV) are an innovative way of making buildings and public structures more energy independent – a practice that is becoming more common as companies become more focused on sustainable energy practices and green building. BIPV installations are used to replace conventional building materials in parts of the building exterior envelope, windows, roof, skylights, or facings to capture solar energy.

One company that has been expanding the use of solar installs in building construction on a global scale is Portugese-based, Martifer Solar. Martifer participated in the installation of 6,00 solar panels on the brand new Mineirão Brazil World Cup soccer stadium (above). The stadium’s photovoltaic installation will produce 1,600 megawatt-hours per year, enough to supply power to 1,200 households. The stadium itself will use 10% of the energy produced by its solar array, with the rest being distributed to local consumers.

The company is increasingly incorporating solar panels into the construction of new buildings to augment or replace grid-based energy.  The seamless integration of solar panels into new, or retrofitted buildings (BAPV / building-applied photovoltaics), can save construction materials and labor costs associated with that portion of the building.

Below are photos of a few more Martifer 360° solar turnkey solutions:

Martifer Solar’s growth reflects the trend toward a transition to production of renewable energy. The company is growing fast and has projects in more than 20 countries over 4 continents that produce a total of over 560MW of photovoltaic solar energy – up from 100MW in 2010. They also specialize in off-grid and small solar power generation projects.

The big picture
Global solar energy production capacity is estimated to have increased by 26% in 2013. The continuing drop in the cost of PV cells is making solar energy much more competitive on a cost basis with fossil fuel energy sources – without the emissions. Every day, we see more and more innovative companies, both large and small, installing renewable production capacity to their headquarters and manufacturing facilities. Some of the largest companies in the world – Google and Apple – are building vast solar and renewable energy capacity to power their businesses.

Renewable energy is the future.

Green Tech: Solar Roadways


solar roadway

Solar panels that you can drive, park, and walk on – that melt snow and cut greenhouse gases – the design and implementation of this clean energy technology is underway and you can become a part of its installation and production. These new Solar Road panels are the brainchild of Julie and Scott Brusaw and their company, Solar Roadways. The panels can be installed on literally any surface and pay for themselves through generating clean electricity. These panels also have other features such as heating elements to stay snow and ice free, LEDs to make road lines visible, and attached “Cable Corridor to store and treat storm water.”

Sandpoint Solar Sidewalk

Solar Roadways has already received two phases of funding from the U.S. Federal Highway Administration for research and development and the technology has been tested for traction, weight, and impact resistance. The panels and company have received several awards and the project looks promising in tackling both (more…)

Clip-On Solar Charger for Power On-the-Go


clip-on solar charger

Have you ever had your phone or camera die when at the beach and a perfect photo opportunity comes up? If this has happened to you, then I have some great news and a unique green solution. OC Outdoor Solar now has a KickStarter program online for you to back the project to make this solution possible.

OC Outdoor Solar will provide a clip on, flexible solar panel that can be attached to and folded into a beach umbrella. What’s great is that this is not just a solution for when you’re at the beach, but also when hiking, at a music festival, or anywhere else – whether or not you use the umbrella with it.

clip-on solar charger folded.

The USB cord is 3 meters in length, which is a little less than 10 feet, which is long enough for you to lounge on your beach towel while having your phone or USB device plugged in. The weight of the solar panel charger is 0.4 pounds, measures 8.5 inches by 18 inches when expanded, and 8.5 inches by 4.5 inches and 1 inch in width when folded, making it easy to take along with you. It will take about four hours in direct sunlight to fully charge a typical smartphone with an empty battery, and if you spend a day at the beach or take a hike I’m sure you’ll be out for longer than this.

I think this product is a great idea, and will be convenient for those who spend a lot of time outdoors and aren’t always near an outlet to charge their USB device. In addition to keeping you charged on the go, charging your gadgets off-grid also has some larger benefits – you will be helping to slow global warming by using less electricity, you’ll save money and you’ll be getting your own little slice of energy independence.
