Testing Hydrogen Fueling Infrastructure

Wednesday, October 19th, 2016

Recently, researchers at the National Renewable Energy Laboratory wanted to know, how well does NREL’s hydrogen infrastructure support fueling multiple fuel cell electric vehicles (FCEVs) for a day trip to the Rocky Mountains? The answer-great! NREL staff took FCEVs on a trip to demonstrate real-world performance and range in high-altitude conditions. To start the trip, drivers filled three cars at NREL’s hydrogen fueling station. The cars made a 175-mile loop crossing two 11,000+ foot mountain passes on the way. Back at NREL, the cars were filled up with hydrogen in ~5 minutes and ready to go again.

Infographic: Here’s How the Grid Works

Friday, October 14th, 2016

With more than 450,000 miles of high-voltage transmission lines (not including distribution lines), the US electricity grid is clearly a behemoth. But how many times have you really given a thought to this huge, incredible network that generates electricity, carries it miles and miles, and powers our Netflix binges, our holiday lights, and our refrigerators? Here’s the breakdown, from the Energy Department:

Investing in sustainable infrastructure is key to tackling the three central challenges facing the global community: reigniting growth, delivering on the Sustainable Development Goals, and reducing climate risk in line with the Paris Agreement…The Global Commission has identified a number of priority actions to rapidly shift investments toward sustainable infrastructure. A number of their previous recommendations are also relevant to this agenda.

Carbon-Cutting Success Stories

Fortunately, leading states continue to prove that curbing dangerous carbon pollution can reduce the risk of global warming and benefit local communities at the same time. The Northeast and Mid-Atlantic states have dramatically reduced dangerous power plant pollution, using tools including the Regional Greenhouse Gas Initiative, a policy that limits pollution over time and makes polluters pay for the privilege of using the sky for waste disposal. Much of the revenue is then invested in clean energy programs, which have boosted the regional economy by nearly $3 billion.

EIA Short-Term Energy Outlook

Tuesday, September 13th, 2016
U.S. gasoline and crude oil prices

Global consumption of petroleum and other liquid fuels is estimated to have grown by 1.4 million b/d in 2015. EIA expects global consumption to increase by 1.5 million b/d in 2016 and by 1.4 million b/d in 2017, mostly driven by growth in countries outside of the Organization for Economic Cooperation and Development (OECD). Non-OECD consumption growth was 0.9 million b/d in 2015, and it is expected to be 1.2 million b/d in 2016 and 1.3 million b/d in 2017.

2016 International Energy Efficiency Scorecard

Wednesday, August 31st, 2016
2016 Energy Efficiency Scorecard - International Rankings

The third edition of ACEEE’s International Energy Efficiency Scorecard examines the efficiency policies and performance of 23 of the world’s top energy-consuming countries. Together these countries represent 75% of all the energy consumed on the planet and over 80% of the world’s gross domestic product (GDP) in 2013. We evaluated and scored each country’s efficiency policies and how efficiently its buildings, industry, and transportation sectors use energy.

The Greatest Energy Story You Haven’t Heard: How Investing in Energy Efficiency Changed the US Power Sector and Gave Us a Tool to Tackle Climate Change

Friday, August 26th, 2016
Figure 1: US Energy Use

An invisible resource is working quietly behind the scenes to provide American families and businesses with the power necessary to live and work. This resource lowers harmful pollution, creates US jobs, reduces energy burdens for those most in need, and strengthens community resilience. It also improves the bottom line for business, returns at least double its investment, and saves American households, on average, $840 dollars a year. Energy efficiency has become the nation’s third-largest electricity resource. With increased support it could become the largest—and one of the world’s core strategies to tackle climate change.

Colorado’s Transit, Biking & Walking Needs Over The Next 25 Years

Monday, August 22nd, 2016
Colorado Investment

Transit, walking and biking are critical components of a 21st century transportation system in Colorado but have been underfunded for decades. Without significant investments in transit, biking and pedestrian services and infrastructure, Colorado will not be able to meet the demands and challenges of our shifting demographics and growing population, and will miss out on the many benefits transit, walking and biking provide.

Emerging Issues: Integrating Solar Energy

Friday, August 19th, 2016
Figure ES-1. Marginal and average PV LCOE (based on SunShot goals) due to curtailment under increasing penetration of PV in California with low and enhanced grid flexibility

Achieving the U.S. Department of Energy’s SunShot Initiative cost targets could greatly accelerate deployment of grid-integrated solar technologies. Global experience with increasing amounts of wind and solar on power systems has shown that variable generation resources can be integrated into the grid at penetrations well beyond current capacity. However, the prospect of dramatically increased photovoltaic (PV) deployment requires detailed examination to ensure that high-penetration solar technologies will provide their intended benefits, including reducing fossil fuel use and reducing the conventional capacity needed for reliable service.
