Local Energy-Water Solutions Should Be A Model For The Nation

Over the past several weeks, I’ve written a lot about the intimate and inextricable connection between energy and water. The energy-water nexus involves a number of technologies, environmental factors and stakeholders. Thus, it’s no surprise that water and energy’s fundamental connection has eluded policymakers for so long. With this post, I review the lessons discussed so far, so that policymakers can understand the key issues surrounding the energy-water nexus and what’s at stake if we fail to act now.

The Bottom Line

Conventional electricity sources, like coal, natural gas and nuclear power plants, require an abundance of water — about 190 billion gallons per day. Because the majority of our electricity comes from these sources, high energy use strains the water system and contributes to Texas’ prolonged drought. Coincidentally, extreme drought could force power plants to shut down.

Climate change is having a profound effect on our weather patterns, making extreme heat and drought more common in Texas and throughout the Southwest. If we don’t set the energy-water system on a sustainable course, we risk a compounded problem.

West Texas Electricity Prices Skyrocket – Demand Response Is The Answer

Source: ENR New York

The Wall Street Journal recently reported that electricity prices in West Texas skyrocketed over 20% this year.  West Texas is home to the Permian basin, one of the world’s largest oilfields, and energy producers use hydraulic fracturing, or “fracking,” here to unlock vast new oil and gas supplies.  The increased drilling, oil refining and natural gas processing uses large amounts of electricity.

Cheaper electricity supplies are available, but cannot be delivered to West Texas due to transmission bottlenecks, or “congestion.”  The only power that can be delivered is from older coal plants.  This leads to transmission “congestion” charges (i.e., higher energy supply costs caused by the transmission bottlenecks), which commercial and industrial consumers must pay as a surcharge on their monthly electricity bills.  Using these older coal plants leads to more pollution as well because these plants burn fuel less efficiently and have higher levels of toxic air emissions.

The typical solution is to build new transmission lines to access cheaper electricity supplies.  But a better and cheaper approach is to pay consumers for voluntarily reducing their electricity usage when energy supplies are tight.  Known as “demand response,” this solution:
