Solar Array Cleaning Robots

Deserts are ideal locations for solar farms – they get a lot of sunshine and the land is relatively inexpensive. On the other hand, their arid nature means that a lot of sand flies around, and sand on a photovoltaic panel blocks valuable sunlight, decreasing its output. Depending on location and weather conditions, dusty panels could […] Read more

White House Holds Solar Summit

Yesterday the White House held a solar summit where it called on businesses and non-profits to support more solar power throughout the U.S. At the summit the President awarded members of the solar community while pushing for more solar deployment and jobs. “Since President Obama took office, we have made significant advances in clean energy,” […] Read more

In Focus: The Hyundai Tucson FCEV

With an EV/HEV/PHEV market projecting a total share growth of up to 4% by end of the year, eco-sellers should be feeling pretty good. However, an innovative product, referred to as theHyundai ix35 Tucson, is quietly rolling into dealerships in the west. Consequently, if reasonable sales numbers follow accordingly, the vehicle’s emergence could signal the beginning […] Read more

Why Taxing Solar Energy is a Horrible Idea

In a setback for the renewable energy movement, the state House in Oklahoma this week passed a bill that would levy a new fee on those who generate their own energy through solar equipment or wind turbines on their property. The measure, which sailed to passage on a near unanimous vote after no debate, is likely to be […] Read more

The Future of American Energy

Imagine a world where homes not only run on clean electricity but also generate, store, and sell it. A world where power companies get paid for conserving energy, not just producing it. Where, when supplies are tight, the power grid gives customers the option of being paid to reduce and even shift their energy use […] Read more

In Focus: Solar Powered Gadgets

At a time when we’re all becoming more dependent on our electronic gadgets, power prices are soaring. It’s hard to imagine life without our laptops, smartphones, tablet computers and all of the other electronics we use every day, and it can be hard to strike a balance between using less power and keeping up with […] Read more

How Crowdfunding and Distributed Generation are Changing Everything

Last year, the Edison Electric Institute released a report titled, “Disruptive Challenges,” which identified current and future serious threats to the  electric utility system. The report identified a number of factors causing the major changes in the electricity industry: Recent technological and economic changes are expected to challenge and transform the electric utility industry. These […] Read more

[…] Read more

Minnesota’s Value of Solar

In March 2014, Minnesota became the first state to adopt a “value of solar” policy. It may fundamentally change the financial relationship between electric utilities and their energy-producing customers. It may also serve as a precedent for setting a transparent, market-based price for solar energy. This report explains the origins of value of solar, the […] Read more

Fracturing Maryland?

The case to ban fracking is growing more popular in a society that is becoming more environmentally aware. Fracking, technically known as hydraulic fracturing, is defined as the process in which “fractures in rocks below the earth’s surface are opened and widened by injecting chemicals and liquids at high pressure: used especially to extract natural gas […] Read more

Home Solar Will Have Another Boom Year in 2014

This year’s outlook for cleaner fuels is bright, according to a recent report from the American Council on Renewable Energy (ACORE). But it is much brighter for some technologies than others. Solar and wind specifically, which remain the cleanest of the cleantechs in the emerging global renewables market, have a very promising future. The same […] Read more

The SunJack 20W Portable Solar Charger

Harold Tan, one of the team members at, has launched a new Kickstarter campaign to build and market SunJack, the world’s most portable 20-Watt solar charger and battery pack for off-grid applications and emergency mobile power.
