New Study Highlights Need for California Market Refinements to Better Harness Clean Energy

By Simi George / Published: February 21, 2017

A new study, jointly conducted by the California Independent System Operator (CAISO) – the entity responsible for overseeing much of California’s electric grid – First Solar, and the National Renewable Energy Laboratory (NREL), demonstrates the untapped potential of utility-scale solar. The study shows that utility-scale solar can provide key services needed to ensure electric grid stability and reliability – better known as ancillary services – at levels comparable to conventional, fossil fuel driven resources.

California needs to reduce reliance on natural gas for ancillary services

In CAISO’s market, ancillary services are overwhelmingly provided by natural gas-fired resources, and their share of the pie has been increasing in recent years.

This growing reliance on natural gas for ancillary services merits attention for many reasons.   Read More »

Saving Energy and Doubling Worldwide Water Supplies – One Drip at a Time

By Kate Zerrenner / Published: February 9, 2017

Netafim HQOn a warm December day, I stood in a jojoba field in the Negev Desert in southern Israel and watched water slowly seep up from the ground around the trees. First a tiny spot, then spreading, watering the plants from deep below. This highly efficient system is known as drip irrigation, and I was there to meet with the world’s leading drip irrigation company, Israel-based Netafim.

Naty Barak, the Netafim director who I met on the visit, notes that if the world’s farmers increased their use of drip irrigation to 15 percent (up from just under 5 percent now), the amount of water available for use worldwide could double.

Drip irrigation saves more than water. Whereas traditional irrigation typically uses quite a bit of energy, drip reduces the pressure (and power) needed to get the water to the crops while reducing the need for energy-hungry fertilizers. Plus, due to the inextricable link between water and power, saving water results in further saved energy.

Texas has already enhanced its water efficiency, but it could go further and take a page out of Israel’s book. By investing in thoughtful drip irrigation now, Texas could lead the nation on expanding this innovative technology and significantly reduce the energy footprint of its irrigation sector, while protecting water supplies for our growing cities and creating more sustainable farming practices.

Texas Leaders Can Use Clean Energy to Increase Investments and Create Jobs. Here’s How.

By John Hall / Published: February 8, 2017

GA_Washington_DC4It’s that time again. Texas leaders are meeting in Austin for the 85th Legislative Session and the next five months will be an interesting wrestling match over human rights, voting rights, bathroom rights, and local rights.

But what about our economic rights? A new report Environmental Defense Fund (EDF) issued to the Texas Legislature, Texas’ Clean Energy Economy: Prioritizing Jobs, Investments, and Growth, shows the Lone Star State’s evolving electricity landscape has created enormous economic growth and jobs. The report explores the policies put in place years ago that has allowed Texas’ power market to become cleaner and more affordable, and it outlines the state’s impressive job growth in energy efficiency, wind, and solar power.

The report urges our leaders to develop and implement a bold, comprehensive Texas energy plan to create well-paid jobs, drive innovation and investment, make us more energy independent, and protect our water supplies, while improving the health of Texans and the environment. Read More »

Rollbacks to National Standards Jeopardize California’s Efforts to Reduce Methane Emissions

By Irene Burga / Published: February 6, 2017

California’s Air Resource Board (ARB) recently released a strong and likely final draft of new regulations that will reduce methane pollution from new and existing oil and gas facilities across California.

CAOilAndGas

Methane essentially is natural gas — wasting it is tantamount to wasting an energy resource. California producers report losing about 75,000 metric tons of methane every year, while nationally companies on publicly owned lands reportedly waste more than $1 million worth of natural gas every day. Alongside methane, oil and gas facilities also emit a list of toxic pollution like hydrogen sulfide, toluene, xylene, and benzene, all of which can be harmful to public health. Read More »

There’s an old expression that whisky is for drinking and water is for fighting over. The Legislative Session is upon us again in Texas, and count on water being an issue, as it always is in this drought and flood-prone state.

To start, this Session will see the approval of the 2017 State Water Plan (SWP), which is done in five-year cycles. In the five years since the last plan, Texas has gone from the throes of a devastating drought to historic flooding, which resulted in some reservoirs being full for the first time in 15 years.

Moreover, as more people move to Texas and climate change advances, there will be greater strain on the state’s water supplies. According to the SWP, Texas is already in a tighter situation than it was just five years ago: Surface water and groundwater availability will be 5 percent lower in 2060 compared to predictions in the 2012 plan, and existing water supplies are expected to drop by 11 percent between 2020 and 2070. Where are we supposed to get the water we need? Read More »

3 Republican Governors Embrace Clean Energy’s Economic Promise

By Dick Munson / Published: January 26, 2017

solar-panels-workers pixabayLast week, the U.S. inaugurated a new president who has vowed to abandon the landmark Paris climate agreement and roll back bedrock American environmental protections.

But turn to the states and you’ll find a different story, even in the red states that elected President Trump. In fact, Republican governors in the Midwest are prioritizing economic growth and job creation by accelerating investments in energy efficiency and renewable energy. In the few weeks after the election, leaders in Illinois, Ohio, and Michigan have adopted new policies that help tackle climate change and grow the clean energy economy. Read More »
