Germany’s Energiewende Proves Electricity can be Clean and Reliable

electric-power-273644_640Since 2004, the year of the first major revision of Germany’s Renewable Energy Act (EEG), the country has added at least 35 gigawatts (GW) of solar and 35 GW of wind to its electric grid – enough to offset upwards of 35 coal plants. What’s more impressive is during the first half of 2014, close to 29 percent of Germany’s electricity came from renewable sources. For perspective, America’s renewables percentage, at about 14 percent, was half of Germany’s during this timeframe.

Meanwhile, the country has improved its status as a grid reliability leader, causing the Heinrich Böll Foundation’s Energy Transition blog to conclude, “Clearly, installing the equivalent of 100 percent of peak demand as wind and solar capacity does not bring down the grid.”  Renewables International further asserts, “Renewables have not yet reached a penetration level that has detrimentally impacted grid reliability.”

This success runs contrary to the predictions of Energiewende’s critics, who have sounded the alarms about investing in “too much” renewable energy. Some of these concerns are more valid than others, but the truth is, most of these claims are blown out of proportion, fixable with solutions that are not overly complex, and/or based on no empirical data.

New Jersey Transit Becomes a Leader in Microgrids

Superstorm Sandy crippled much of New Jersey’s critical infrastructure when it swept through the state two years ago. Stuck without power at home, many of the state’s residents also couldn’t get to work because the operations center for New Jersey Transit (NJ Transit) flooded, damaging backup power systems, emergency generation, and the computer system that controls train operations.

New Jersey is doing its best to make sure that won’t happen again. After a highly competitive grant process, NJ Transit last week received $1.3 billion in federal funds to improve the resilience of the state’s transportation system in the event of devastating future storms. The funds include $410 million to develop the NJ TransitGrid into a first-of-its-kind microgrid capable of keeping the power running when the electric grid goes down.

Microgrids are different from traditional electric grids in that they generate electricity on-site or nearby where it’s consumed. They can connect to the larger grid or island themselves and operate independently. Read More »

Resiliency+: Smart Grid Technologies and the Benefits of Two-Way Communication

PowerGrid_large_outlinesIt’s September, fall is around the corner, and with it, the second anniversary of devastating Hurricane Sandy. A smarter, more efficient electric grid should be on the minds of all New Jerseyans. Unfortunately, it’s not.

Wired magazine calls America’s power grid the largest machine ever built. Over the past few decades, this grid has been expanded throughout the country to ensure that even remote areas have electricity. Although this is an incredible accomplishment, the grid should also strive to keep pace with the latest technological advances, becoming not just the largest machine ever built, but also a more efficient and resilient one.

Elon Musk’s Love-Hate Relationship with Texas

For months now there has been much secrecy and mystery surrounding the location of electric car revolutionary Tesla’s new $5 billion Gigafactory. The factory will supply cheaper batteries for the company’s Model 3 electric car and will be large enough to manufacture more lithium-ion batteries than the entire industry produces now. Due to its sheer scale, the factory is expected to reduce the cost of batteries by almost one-third and create close to 7,000 jobs directly and thousands more indirectly.

Amidst all the rumors abounding, closed door meetings, and tax break wars, I wrote about Tesla’s search for the perfect factory location – of which Texas was in the running. Despite Tesla breaking ground near Reno, Nevada a few weeks ago, there was still speculation about where the Gigafactory might be located, and Texas’ chances remained somewhat alive.

But no more. Tesla indeed confirmed that Reno will be the home of the Gigafactory. This is great for Nevada’s economy, but as a Texan, it still feels like a bit of a blow – though I’m not surprised.

While Texas Governor Rick Perry personally lobbied for the Gigafactory to make its home in Texas, it doesn’t help that he’s at the helm of a state hostile to clean energy, despite leading the nation in wind power. Although I’m hopeful that future clean tech endeavors will come to Texas, the existing status quo needs to change to combat this hostility.   Read More »

McKibben and EDF Agree: Plugging Methane Leaks “A Huge Priority”

Methane is flared from a natural gas well site.

Methane is flared from a natural gas well site.

Bill McKibben is at it again—using his formidable analytical and rhetorical skills to challenge comfortable climate assumptions. In this case, the author and activist puts the heat on politicians, including Barack Obama and Hillary Clinton, who argue that natural gas can be a “bridge fuel” to a low-carbon energy future.

Since natural gas emits half the carbon of coal when it’s burned, supporting it gives politicians a way to position themselves as both pro-energy and pro-climate. But writing in Mother Jones, Bill questions whether switching from coal- to natural gas-fired electric generation brings any climate benefit at all.

Because natural gas is mostly methane, a potent greenhouse gas, he points out that if enough uncombusted methane is leaking from the natural gas supply chain, natural gas may be even worse for the climate than coal.

We couldn’t agree more. Read More »
