The 50 Most Innovative New Renewable Energy Companies

To make our list, your company had to be, first and foremost, innovative. Your company needed an innovative product, technology, or process to even have been considered for our rundown.

What is an Ice Battery?

Home ice batteries have the potential to transform the electric grid by enabling utilities to gain visibility and control over the largest residential peak load - cooling.

High legal barriers in 10 states make it especially difficult to put solar panels on rooftops.

Julian Spector for CityLab:  A lot has been said already about the success of the states that are leading the adoption of solar energy. There’s plenty to celebrate, as solar installationssmash records and as the industry grows 12 times faster than the U.S. economy. At the same time, it’s important to recognize that many people live in places where the government is either not facilitating a solar market or is actively smothering it. Solar obstructionism takes center stage in a report, aptly titled “Throwing Shade,” out Tuesday from Greer Ryan at the Center for Biological Diversity. The organization advocates for an energy system that’s clean, equitable, and wildlife friendly, so Ryan set out to rank the states based on how well their policies encourage rooftop solar panels. Then she analyzed the 10 worst-scoring states with the highest solar potential in order to better understand how the absence of state-level policies—or the presence of antagonistic ones—hampers the growth of solar markets.   Cont'd...

Wind generation growth slowed in 2015 as wind speeds declined in key regions

EIA's most recent Short-Term Energy Outlook projects that wind generation will increase 16% in 2016, as significant capacity additions are expected to come online, adding another 6 GW, or 9%, to operating wind capacity in 2015.

Energy Storage - Lithium Iron vs Lithium Ion Battery Applications

There are several key differences between the Iron Edison Lithium Iron battery and the Tesla Powerwall. First, an Iron Edison Lithium Iron battery is available in traditional nominal voltages of 12V, 24V and 48V, making it fully compatible with common battery-based inverters and charge controllers from major manufacturers like Outback, Schneider Electric, Magnum, MidNite Solar and SMA.

Permanent Magnet Technology: The Wind Industry's New Drive Train Standard

As PMG+FPC drive trains outperform DFIGs from both a full-cycle cost-efficiency and reliability perspective, the turbine manufacturing industry needs to revise some of its old assumptions and obsolete turbine technology choices to embrace the generator technology that leads to better AEP.

The Birth of Thermodynamics

Here is an account of something I stumbled upon on a visit to Munich last year which I hope will be of interest. The four laws without which nothing whatsoever throughout the universe that happens, happens.

What is Hydropower in a Pipe?

According to the US Geological Survey, 66% of public water comes from surface water. Presumably some of that is pumped at some point, but even if only half of that were gravity fed, the potential for electricity production from municipal water pipes is significant.

Manage Costs and Risks With Long-Range Probabilistic Weather Forecasts

Deterministic weather forecasts have their place, but probabilistic forecasts are the clear choice for alternative energy companies that take the weather seriously and need long-term data.

Tesla And Other Tech Giants Scramble For Lithium As Prices Double

And while lithium has traditionally been controlled by a handful of major global suppliers, spiking demand is changing this landscape drastically.

Is the U.S. Still Addicted to Oil?

Universal access to renewably-generated electricity could be within the foreseeable future, with cleaner air and water as the side effects. Better public transportation systems will make life more enjoyable for commuters all over the country, as will a self-sustaining energy economy.

This Device Could Provide a Third of America's Power

Sam Grobart for Bloomberg:  There are 332,519,000 cubic miles of water on the planet. That's 352,670,000,000,000,000,000 gallons just sloshing around out there.  Anyone who's ridden or been tossed by a wave has a sense of the kinetic energy contained in our perpetually moving oceans. If we could harness it, it could provide a clean, renewable source of energy. But efforts to turn our oceans into power generators—often in the form of "aqua-mills," windmill technology adapted to water—have foundered on the complexity of their many moving parts in the corrosive and remote environs of the sea.  A new approach, developed by a company called Oscilla Power, applies all that kinetic energy to a solid piece of metal instead of using it to turn the blades of an impeller. That creates an alternating magnetic polarity in the metal that can be converted into electrical current.  Oscilla's technology, which is nearly solid-state, may prove far more durable than any other ocean-power project, increasing the chance to draw power from our oceans cleanly, meaningfully, and endlessly.   View video here:
