Hurricane Sandy proved that New York City’s energy system is not up to the challenges of the present day.  And, as we have highlighted before, the city faces some major challenges to reducing dangerous air pollution caused by heavy heating fuels.  One promising solution seeking to significantly reduce NYC’s carbon footprint, improve air quality, and increase grid resiliency during storms is geothermal heat pumps.

The U.S. Environmental Protection Agency (EPA) has called ground source heat pumps the “most energy-efficient, environmentally clean, and cost-effective space conditioning systems available.”  Geothermal heat pumps or exchangers, also known as geo-exchange, require no fossil-fuel burning on-site, use 70 percent of their energy from Earth’s renewable sources and are, on average, nearly 50 percent more efficient than gas furnaces.

Last month, I had the honor of watching NYC Mayor Bloomberg sign a bill tasking the New York City Office of Long-Term Planning & Sustainability to study geothermal energy resources and the feasibility of city-wide adoption of geothermal heating and cooling.  As Mayor Bloomberg’s sustainability leadership – in an official capacity at least – comes to an end, his plans to ensure that the city’s mission to find sustainable, cost-effective solutions to combat air pollution are well underway.  Though the geothermal heating and cooling bill is very important, it is only one aspect of the Mayor’s larger PlaNYC effort.

During his speech, Mayor Bloomberg remarked, “So what is geothermal anyway? I am having it installed in the new place I just bought and I know it works and how much it costs but nothing else.”  His words sum up the greatest challenge for geo-exchange yet – lack of awareness.  Geo-exchange technology needs our help to move it out of its prolonged infancy and into the mainstream.

New York City’s Air Is Well On Its Way To Becoming Cleaner Than Ever

NYC Clean Heat is halfway to achieving its goal of reducing harmful heating oil soot pollution in New York City by 50 percent by the end of 2013.

The NYC Clean Heat program experienced tremendous growth in 2012. The Mayoral announcement in June 2012 marked the official transition from the pilot phase to full implementation of the NYC Clean Heat program, which aims to clean the air in New York City by helping buildings convert from highly-polluting No. 6 and No. 4 heating oils to the cleanest available fuels. The heating oils used in one percent of New York City buildings create more soot pollution than all the cars and trucks in the City combined – that’s why upgrading these buildings to cleaner heating fuel is the single largest step New Yorkers can take to solve local air pollution.

The goal of NYC Clean Heat is to cut heating oil soot pollution in half by the end of 2013. NYC’s Department of Health estimates that achieving this goal will result in over 120 lives saved each year and prevent hundreds of emergency room visits and hospitalizations for respiratory and cardiovascular conditions.

I’ve been a part of the NYC Clean Heat team for almost two years now, and I can tell you that I am floored by the progress we’ve made. For instance: 

  • By the end of 2012, over 1,200 boilers – well beyond the number of conversions the regulations required – have switched to natural gas or ultra-low sulfur No. 2 (some of the cleanest available fuels), and over 2,000 additional boilers in line to convert.
  • These 1,200 conversions have resulted in over 150 tons of reduction of soot pollution, or particulate matter (PM2.5), which is equivalent to removing over 800,000 light-duty passenger vehicles from the road for 1 year. That’s over 13 billion miles travelled!
  • NYC Clean Heat won the 2013 Citizen Budget Commission’s Award for Public Service Innovation.

Why is all of this important? Approximately 1,500 buildings still need to complete conversions in 2013. Also, roughly 2,000 permits for No. 6 oil are set to expire before March 2014, representing 232 tons of soot pollution. Because this week is National Public Health Week, we are more aware than ever of what reducing air pollution in New York City will mean. NOW is the time to take action. Read More »

EDF And Others Honored For New York City’s Carbon Emissions Video

Source: Carbon Visuals

Last week, Environmental Defense Fund (EDF) and Carbon Visuals, a UK-based firm (brought to EDF’s attention by Power Angels) dedicated to “communicating carbon data more effectively,” were honored by American Clean Air Skies Foundation at their awards gala to commemorate videographers and web-based innovators for works that bring climate change and energy resources to mainstream media.  Carbon Visuals produced a video, funded by EDF, which encapsulates, literally, New York City’s (NYC) carbon emissions in a year’s time.  The video shows blue bubbles as they multiply and expand to cover NYC’s skyline over the course of an hour, day and year.  It was designed to engage everyday people who use energy (which is everyone!), helping them to visualize the magnitude of carbon emissions emitted in order to better understand why we must act NOW to accelerate the transition to the clean, low-carbon energy economy we need to avoid climate catastrophe.

This visually impactful video was made possible with the support of NYC and its exemplary effort to track and reduce greenhouse gas emissions.  The City of New York provided a report from September 2011, Inventory of New York City Greenhouse Gas Emissions, documenting the 54 million metric tons of carbon dioxide (CO2) – the principal contributor to man-made climate change – NYC added to the atmosphere that year.  The building sector alone contributed approximately 75 percent of the emissions, with the bulk of the remainder attributed to the transportation sector.  While these figures may seem irreversible, NYC and Mayor Bloomberg have made considerable strides to reduce emissions in one of the most energy-intensive cities in the world. For instance, emissions in 2010 were 12 percent less than 2005 emissions, and NYC continues to stay on track to reduce emissions by 30 percent by 2017 – a commendable target.

Bloomberg’s State Of The City Ideas Good For Health And The Environment

Source: CBS New York

A lot happened yesterday: Brooklyn Nets cheerleaders. Jay-z soundtrack. Kids dancing on stage. The new stadium at Barclays Center. Popcorn. Valentine’s Day. Mayor Bloomberg’s birthday? Yes. But also his last State of the City speech.

In his speech and a small briefing in advance, he identified recent environmental wins: clean heat’s 170 tons of soot per year gone so far, a 16 percent cut in GHG pollution since 2005, the monumental third water tunnel under city streets, new waterfront parks underway at Fresh Kills, Governors Island and Brooklyn Bridge Park.

Mindful of 320 days left in his term (this guy counts data), he announced some ideas that can get done now:

  • Electric vehicles. A network of charging units citywide with 30-minute charges — one third of NYC’s taxi fleet to be electric. New York City could become a great place to charge a Tesla, a Leaf or a Volt. With traffic just behind heating oil as the main reason why some neighborhoods have unusually high pollution, that’s a good idea for health and climate. It also opens a conversation about the electric grid that extends well past his term. Will those cars run on electricity created by solar, hydro, wind, nuclear, natural gas, coal? Here’s an example of how to get it right: Pecan Street Inc.
     
  • Recycling. Expanded recycling for plastic, including those take-out containers so familiar to New Yorkers.  And – an issue that’s getting a bit of press – ridding our city of styrofoam cups used in schools, delis and restaurants.   This reminds me of EDF’s work with McDonald’s many years ago, getting rid of the Styrofoam clamshell.
     
  • Third, a citywide bike share program, to launch this summer.  This could end up being one of the largest bike share programs in the world.

Equally interesting are some of the ideas not explicitly framed as “environmental,” for instance:

  • A post-Sandy commitment to “rebuilding here,” on the waterfront — but doing so sustainably, in a way that “keeps the lights on” in a storm. That will take unprecedented collaboration with state and federal policy makers, tech innovation, architecture and design and efficiency finance.  A first step is to make sure that federal dollars flowing in to the region after Sandy are spent in a way that helps local communities make fully informed choices about not just “where” to rebuild, but “how” to rebuild.
     
  • And an idea that could reshape the skyline for a long time: “Midtown rezoning.” Sound boring? Could be.  But imagine midtown Manhattan with buildings that are far at the forefront of resilience and clean energy – taking full advantage of the latest technologies to generate clean electricity and waste as little as possible. Could Manhattan be the next Pecan Street? This is an opportunity not yet fully-seized. Read More »

Weathering The Storm Next Time: Gov. Cuomo’s NYS 2100 Panel Offers Smart Plan To Keep The Lights On, Emissions Down

Extreme weather and aging infrastructure came together with a vengeance in Sandy, showing the fragility of the basic systems that sustain this vibrant city and region. Like so many others, my family lost power, heat and water during Superstorm Sandy, and I watched out my window as a giant flash marked the moment that waters crested a 12-foot retaining wall at the 14th Street ConEd plant.

New Yorkers are all too familiar with the devastation that followed, and the disruption that spread far beyond the water’s reach. As the immediate crises are resolved, our attention is now on the complex challenge of long-term resilience.

One big step: The NYS 2100 Commission, a panel of experts assembled by New York Gov. Andrew Cuomo back in November, just two weeks after the storm. EDF President Fred Krupp served on the commission, and our energy team prepared extensive recommendations on how to make our energy system more robust, resilient and adaptable. In yesterday’s State of the State address, he talked about the results.

As it turns out, some important solutions were right under our noses.

For example, amid the darkness and devastation, there were dozens of homes, businesses, even whole communities that kept their lights on and the water because they were designed to isolate breakdowns, heal quicker, and work with natural systems rather than against them.

Success stories were located across our region: 

  • Lights stayed on for sixty thousand residents of Co-op City in the Bronx thanks to a combined heat and power plant that can operate independent of the grid. Ditto the office tower at One Penn Plaza, an apartment building at 11 Fifth Avenue, and large parts of the campuses at Princeton and NYU. 
  • In Bayonne, NJ, the Midtown Community School used a combination of solar panels and a generator to offer a safe, warm place to stay for over 50 residents during the storm. 
  • On Long Island, the Villani family kept their lights on thanks to a 4.8 kw solar array that happens to have a battery bank. “We had friends and neighbors coming over to charge phones and batteries,” Stephanie Villani said. 
  • In lower Manhattan, the community group Solar one used solar panels to offer residents of Stuyvesant Town, the sprawling 35-building apartment complex, a place to charge their phones and computers.

Exceptions like these should be the rule next time. Unfortunately, today’s utility grid is set up to discourage more of these success stories – which are also cleaner and more efficient.

In fact, many buildings outfitted with fresh new solar arrays stayed dark thanks to cumbersome, outdated rules and regulations. Ironically, the solar panels were not making electricity when the grid was down, precisely because they were permanently connected to the grid and had to be shut down, rather than simply unhook when the larger system failed. So instead of sunshine, they were running on diesel power – if they were running at all.

Building a smarter grid, and encouraging clean, efficient ‘microgrids’ that provide islands of heat and light means fewer outages and faster recovery. A smarter grid would also have the intelligence needed to pinpoint outages, cordon off damage, and reroute power.

Clearing out the legal cobwebs and requiring utilities to unlock their grids more easily would make their systems stronger and more resilient in a crisis, and open the door for more efficient, renewable energy solutions. It would also open up opportunities for new ways to finance the upgrades needed to take full advantage of efficiency and renewables in today’s buildings.

(You can read EDF’s blueprint for a smarter, more robust grid here.)

Climate change means that higher sea levels and more extreme storms are the new normal. Unfortunately, some of this is already locked in. But we still have an opportunity to prevent the worst, most costly consequences by working together to reduce heat-trapping pollution. Superstorm Sandy reminded us of the need to prepare for a more challenging future. We need to make sure the steps not only protect against the impacts we can’t avoid, but also help prevent those we can.

Yes, we will have to fortify our buildings and infrastructure, change building codes and keep generators on hand in the face of extreme weather. But a lot of the steps we can take to keep the lights on during a crisis are also steps we can take to cut the pollution that is linked to climate change and extreme weather in the first place.

As we invest federal emergency dollars to rebuild, as we get ready for the next time – let’s make sure we’re taking every step that solves for both safety and less pollution at the same time. Efficiency, a smart grid, transparent information, renewables. Unlocking multiple benefits like these can help us rebuild better, faster and stronger. And lead the way for the world’s great cities, many of which are on the coast and in harm’s way just like New York.

My kids and I were lucky to weather the storm with just inconvenience. But as I think about how might live in a future New York City, I’d like to be sure that we’re doing everything we can now to run this town on safe, clean energy. The Cuomo commission report takes a big step in that direction: let’s join the Governor and the members of this commission in making its recommendations a reality. This is an opportunity that business, political and community leaders must not miss.

New York’s Decision To Take Time For A Public Health Review Of Hydraulic Fracturing Is A Wise Move

Last week’s announcement that New York State Department of Environmental Conservation (NY DEC) has asked New York State Department of Health (NY DOH) to undertake a review of the work NY DEC has done to date on regulating high volume hydraulic fracturing is welcome news.  Citizens across New York have raised legitimate questions about whether NY DEC is doing all that it can do to develop regulations that protect public health.  Review by a qualified panel of public health experts, under the auspices of NY DOH, is a necessary step to answer these legitimate concerns.  Getting the rules right in New York is critically important, so we believe that taking the time for a public health review is a wise move.

Of course, it is critically important that this review be done well.  The experts convened by NY DOH should be qualified, independent public health professionals.  The scope of their review should be broad and the work that they do should be thorough.  Science, not politics, should guide their work.  Above all, NY DEC should stand ready to act on any recommendations that come from this review.  EDF looks at this an opportunity to make NY DEC’s good work to date better, and we hope NY DEC sees it that way too.

EDF believes that New York’s regulatory regime should include the development of a public health baseline across the communities where shale gas development would be likely to occur, coupled with a rigorous, on-going effort by NY DOH to track key public health metrics against this baseline over time.  We believe this step is necessary to assure that regulations are working to protect public health, and provide the data necessary to fix them if they are not. 

No community should have to sacrifice public health or the quality of their environment for the sake of energy production.  Nor should artificial deadlines cut short efforts to get the regulations right.  New York Department of Environmental Conservation deserves praise for taking this necessary step.
