It’s Time Our Policies Reflect The Fact That Energy And Water Are Fundamentally Intertwined

By Kate Zerrenner / Published: July 11, 2013

When I tell people that the best way to conserve energy is to conserve water, I am often faced with a confused response.  I’m not surprised really.  Energy and water policies are rarely discussed in the same forum.  For a long time, we’ve overlooked the inextricable relationship between water and energy use.  Coal, nuclear and natural gas plants use enormous amounts of water for cooling purposes.  In 2005, 41% of all freshwater withdrawals in the nation was used in the thermoelectric power industry for cooling.

Connection between energy and water

The longstanding division between energy and water considerations is particularly evident in the case of energy and water management.  These resources are fundamentally intertwined: Energy is used to secure, deliver, treat and distribute water, while water is used (and often degraded) to develop, process and deliver energy.  Despite the inherent connection between the two sectors, energy and water planners routinely make decisions that impact one another without adequately understanding the scientific or policy complexities of the other sector.  This miscommunication often hides joint opportunities for conservation to the detriment of budgets, efficiency, the environment and public health, and inhibits both sectors from fully accounting for the financial, environmental or social effects they have on each other.

This lack of collaboration between energy and water planners is especially dire considering Texas is in midst of an energy shortage that is exacerbated by the multi-year drought.  Without adequate planning, we could someday have to choose between keeping our lights on and turning on the faucet.

I love California in the summertime, and Fourth of July weekend is one of my favorite holidays. But it is getting excruciatingly HOT out here, and according to the best science, it is going to get much hotter.

This past weekend the West Coast broke nearly every temperature record on the books, well ahead of August and September, which are usually the hottest months of the year.

And last year was the hottest year on record for the continental United States. Crops were devastated, cities were hit by supercharged storms, and people, mostly the poor, suffered and died amid some of the most destructive extreme weather events in our history. All told, the United States spent more than $110 Billion on weather related disasters in 2012.

There’s more bad news ahead. Extreme heat projections for the U.S. in 2030, based on research from Stanford University, shows that the West and Southwest are going to get really, really hot! Read More »

Energy Capital Of The Nation Turns To Clean Energy

By Elena Craft, PhD / Published: June 27, 2013

This commentary originally appeared on EDF’s Texas Clean Air Matters Blog

Last week, the City of Houston announced that it would increase its purchase of renewable electricity to cover half of its energy use.  The city will use almost 623,000 megawatt-hours of electricity from renewable sources per year—equivalent to the energy used by 55,000 residential homes annually.  The purchase makes Houston the largest municipal buyer of renewable energy in the nation.  While Houston’s latest renewable energy purchase may seem at odds with its reputation as an oil and gas hub, it’s exactly the sort of common-sense decision we expect from a city that’s touted as the energy capital of the nation.

Houston is in good company among other Texas cities. The City of Austin already gets 100% of its electricity from renewable sources.  To make the switch, the city leveraged Austin Energy’s GreenChoice program, one of the nation’s most successful utility-sponsored and voluntary green-pricing programs.  The program is part of Austin’s Climate Protection Plan, which establishes a 35 % renewable portfolio goal for Austin Energy by 2020.  In San Antonio, the municipally owned CPS Energy has emerged as a leader in clean energy. Through its New Energy Economy initiative, CPS Energy is growing its network of smart meters and expanding its installed solar capacity, among many other sustainable initiatives.  Today, CPS Energy uses more solar energy than any other Texas utility, while still having the lowest electric rates among the top 10 largest cities in the United States.

“Heck Yes”– Millennials Respond to the President’s Call

By EDF Blogs / Published: June 27, 2013

 

This commentary originally appeared on the EDF Climate Corps Blog

By: Katie Ware, EDF Senior Marketing Communications Specialist

The environmental community is abuzz with reactions to President Obama’s wide-ranging Climate Action Plan. His speech introducing the plan Tuesday sparked immediate conversations about the Keystone XL Pipeline, the coal industry, the transportation sector and half a dozen other hot button environmental issues.

For me, his speech hit home in the first minute. Addressing the crowd at Georgetown University, he said he wanted to speak directly to my generation “because the decisions we make now and in the years ahead will have a profound impact on the world that all of you inherit.”

Confident, connected and open to change (says Pew), we Millennials are 95 million strong. We elected and then re-elected Obama looking for precisely this type of bold action on issues we feel passionately about.

“Someday our children and our children’s children will look us in the eye and ask did we do all that we could when we had the chance to deal with this problem and leave them a cleaner, safer, more sustainable world. I want to be able to say yes we did. Don’t you want that?” he asked.

My answer to the President is, heck yes, and my peers are with me. Read More »

President Obama’s Plan To Accelerate The Transition To A Clean Energy Economy

By Jim Marston / Published: June 25, 2013

Today President Obama took an important step toward meeting the promise of his inaugural address to “respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations.”  The headline, of course, is the commitment to take serious action to address the most significant challenge our generation faces – climate change. And, with it, the extreme weather and public health burdens that are already making life harder for vulnerable regions and people nationwide, and that stand to become so much worse as the root cause remains unaddressed.

In his Climate Action Plan announced at Georgetown University, the President laid out his vision for putting in place common sense policies that will cut harmful carbon pollution while driving innovation, cutting energy waste and energy bills, creating jobs and protecting public health. 

Most Americans would be shocked to know that there are no current limits on carbon pollution from power plants. By setting the first standards in history for carbon pollution from power plants in the United States – which produce 2 billion tons of this pollution each year, or about 40% of the nation’s total – the President will help modernize our power system, ensuring that our electricity is reliable, affordable, healthy and clean.  And we can do this in a way that can give industry the flexibility it needs to make cost-effective investments in clean energy technologies.

A modern, intelligent, interactive electricity system will help minimize problems that arise from extreme weather events and other disruptions and maximize renewables, efficiency and consumer choice.  Since the President took office, our country has seen the beginnings of a revolution in the energy sector – technological innovations have put us on track to energy independence and clean, homegrown energy resources constitute a growing share of electric generation capacity.  Reducing wasted energy and using more clean energy offer enormous potential for our health, economy and climate, including:

–          Little to no harmful pollution = improved public health

–          An unlimited, homegrown energy supply = less reliance on foreign oil

–          Economic development = more jobs

–          Stable energy prices = lower electric bills and improved economic stability  

–          A more reliable, resilient energy system = less costly, scary blackouts

–          A global leadership position in the multi-trillion dollar clean energy economy = reclaimed pride and competitiveness for America’s manufacturers

NYC’s Storm Preparedness Means Rethinking How We Make And Use Energy

By Andy Darrell / Published: June 20, 2013

This commentary, authored by Andy Darrell, originally appeared on EDF Voices.

Last Tuesday, I caught a ferry from the lower Manhattan waterfront (just south of the substation that shorted out so dramatically in the midst of Hurricane Sandy) to the Brooklyn Navy Yard. There, Mayor Michael Bloomberg unveiled his vision of a New York that will be far better able to withstand the battering from giant storms that, thanks to climate change, are likely to arrive with increased frequency and fury.

The Mayor began by noting some stark facts:

  • “We expect that by mid-century up to one quarter of all of New York City’s land area, where 800,000 residents live today, will be in the floodplain.”
  • “[Wi]ithin FEMA’s new 100-year flood maps there are more than 500million square feet of New York  City buildings – equivalent to the entire city of Minneapolis.”
  • “About two-thirds of our major substations and nearly all the city’s power plants are in flood plains today.”
  • “A day without power can cost New York City more than a billion dollars.”

A lot of media attention in the wake of the speech focused on Bloomberg’s call for levees and seawalls to keep rising waters at bay. But embedded in the address was also an ambitious but practical rethinking of how New York City makes and uses energy. The plan frames a future in which solar, wind and microgrids play a much larger role in the city: Read More »
