Texas Cities Lead on Solar, But Tapping The State’s Potential Has Just Begun

Mueller_austin_solar_array1Last year solar power saw unprecedented growth and it doesn’t seem to be slowing down. So where is much of this growth happening? In one word: cities.

In a new report from Environment America Research & Policy Center and Frontier Group, Shining Cities 2016 identifies the urban centers fostering growth in solar energy, and the policies and programs that can maximize solar potential. The cities that topped the list were, not surprisingly, primarily from the sunshine-abundant Pacific region, followed by an equal amount of cities from the Mountain, South Central and South Atlantic regions. These centers of connectivity and growth are major electricity consumers, and therefore important movers in the transition to a clean energy economy.

But there are still vast amounts of untapped solar potential in the U.S. – specifically 1,118 GW, which equates to 39 percent of total national electricity sales (enough to power over 782 million homes a year) – according to a study on “rooftop solar power generating capacity potential” by National Renewable Energy Laboratory (NREL). The same study stated that Los Angeles, the city currently with the most solar capacity, could host up to 42 times its current solar capacity, providing up to 60 percent of the city’s electricity. This staggering amount of renewable energy is possible in other cities across the U.S. as well – even in unlikely states, such as Texas. Read More »

We’re wasting solar energy because the grid can’t handle it all. Here’s a solution.

caligrid_378x235California has a nice problem: It’s producing so much clean solar energy that the state’s electric grid is at capacity, and sometimes beyond.

As Vox’s David Roberts reports in his excellent piece about California’s grid headache, it makes good sense to expand the system by interconnecting state-run energy markets.

But he also notes, at the end of his story, some other and complementary strategies California can use to increase its grid bandwidth – while accommodating rapidly growing, but variable, renewable energy sources.

Connected grids, alone, are not a long-term fix. Read More »

Why Texas Leaders Should Maintain Clean Energy Tools

wind turbines unsplashIn terms of clean energy, Texas is incredibly resource-rich. And as our wind progress shows, we have begun to maximize that potential: The Lone Star State currently produces nearly three times as much wind energy as the next highest state.

How did Texas arrive at the forefront of the wind energy economy? One factor that undoubtedly played a vital role: the creation of an ahead-of-its-time policy tool that required the identification of Competitive Renewable Energy Zones (CREZ), as well as the construction of transmission lines to move energy from the CREZ to electric customers.

Since West Texas has plentiful wind but not as many people, this initiative aimed to transport that wind energy to populous cities throughout the state. The rules allow the Public Utility Commission of Texas (PUCT) to designate an area with abundant renewable energy as a CREZ, and then approve new transmission lines or improvements to existing ones. In 2008, the PUCT exercised this authority and the resulting power lines – completed in 2014 – stretch nearly 3,600 miles, moving clean, renewable energy across the state while improving the overall reliability of the electric grid.

However, despite these successes, the PUCT recently proposed to dismantle the rules related to CREZ and the approval of new transmission lines, which would be a significant affront to the state’s thriving wind industry – including the revenue and jobs that come with it. Right now, there are no proposals to expand the designation of CREZ and develop additional power lines to those zones. But with the rapidly changing energy landscape, it makes more sense for state leaders to maintain CREZ capabilities in their toolkit, rather than undoing a successful energy development policy.

Transforming an Energy Burden into an Energy Opportunity

Energy opportunityEconomic inequality has become one of the dominant political narratives of the day. It occupies discussions on both sides of the aisle, and is shaping elections from city halls to the White House. There’s a good reason for this: the continuing trends of flattening incomes, concentrated wealth, and deepening poverty are historic.

One place this reality is really hitting home for millions of Americans is on their monthly energy bill. For nearly one in three American families, paying a monthly energy bill is a challenge.

The energy burden, as the Department of Energy defines it, is the ratio of energy costs (which includes heating, cooling, appliances, and lighting from electricity, gas, and fuel sources) to household income. Nearly 40 percent of low-income households use electricity to heat their homes (the majority in the South and West), and are suffering a more severe energy burden because of factors like wage stagnation and the quality of housing at lower economic levels.  In 2014, researchers looking at the “energy affordability gap” for low income households (the difference between actual energy bills and what is considered affordable) tabulated it at almost $45 billion nationally. That is an increase of 16 percent from 2011, with nearly 60 percent of the growth accounted for by states in the mid-South, South, and east of the Mississippi. For any of those families, even a 10 percent growth in electricity costs can be destabilizing. Monthly electric bills become another factor forcing households to choose between groceries, childcare, and medical bills.

To make inroads in closing the energy affordability gap and reducing energy burdens for the most vulnerable, Environmental Defense Fund believes we need a combination of greater and scalable clean energy investment in low- and moderate-income communities, and a focus on empowering the many faces that are energy-burdened. The multi-billion dollar affordability gap certainly poses a variety of financial risks, but it’s also rife with opportunity. Read More »

Forget Taco Wars – the Real Competition is Over Who is Using Water More Wisely

Guadalupe_river_Hunt_TXSan Antonio and Austin just called a cease-fire on a taco war over which city invented the breakfast taco. Both make excellent tacos: from the traditional chorizo and egg taco in San Antonio to a free-range egg and organic spinach taco in Austin. But this debate was about more than just tacos – it was about the history and culture of these two neighboring cities.

Only 80 miles apart, San Antonio and Austin have some significant differences. San Antonio is known as “Military City USA” largely due to its huge military bases, but it’s also known for other industries like biotech, military medical centers, and a dynamic business relationship with Mexico. The capital city’s economy, on the other hand, is based on high-tech, entertainment, state government, and the behemoth University of Texas at Austin. San Antonio is one of the largest Hispanic-majority cities in the country (at 63 percent in 2010), while Austin’s diversity comes in large part from people flocking to the Capitol from all over the state and country. As someone with roots in both San Antonio and Austin, I appreciate both – I’m an equal opportunity taco lover.

But both cities share an important commonality: exploding population growth. The population of the 13 counties that make up the Austin-San Antonio corridor is estimated to increase by 77 percent by 2050, to 6.8 million people. Extreme growth brings intense pressure on resources and services, particularly water in this drought-prone region. Both cities are standing up to that challenge through careful water conservation measures and by advancing clean energy. Read More »

The Sun Belongs to Everyone

2016-03-03-1457029192-4192505-GRIDsolar1

I thought only supervillains like Mr. Burns or Supreme Leader Snoke from Star Wars were bold enough to try snuffing out the sun…I was wrong.

I’ve been writing about solar power and economic equity for eight years now and I still firmly believe the vision that drew me to this issue in the first place: solar and other forms of clean energy hold the potential to be a jobs and economic growth machine for communities who need it the most.

Back in 2008, I joined a collective movement of environmentalists, community and justice activists, and labor and faith groups who coalesced around a vision for the “green collar economy.” The idea of this movement was to fight climate change while also lifting people out of poverty and jails, and helping them transition into promising careers in growing industries.

Since then I’ve seen many great strides in the creation of a clean energy economy that employs hundreds of thousands with well-paying and accessible jobs, propelled by smart policy, innovation, and upstart private and public sector players, all making meaningful investments in communities. Rooftop solar in particular has begun to challenge the status quo by turning people’s homes into mini power plants, cutting into dirty power and the monopoly-dominated, electric grid.

Yet, despite this progress and opportunity, some states – fueled by short-sighted officials, fear-mongering, and the threat of declining profits for big business utilities – want to shut it all down. Read More »
