Climate change: How US cities are already feeling the effects
A new UN study shows climate change is no longer a hypothetical of the future. Here’s how it’s already affecting regions across the country and what you can do to prepare.
Just the FAQs, USA TODAY
Single-family homes represent about 70% of residential buildings and almost 20% of U.S. energy consumption, both in Texas and nationwide. Yet they remain an untapped resource in curbing emissions.
Much of this demand is for energy that heats and cools our homes, and it is primarily met by fossil fuel-based power plants that contribute to climate change. But our homes also hold immense potential to help mitigate these climate impacts if we harness this potential intelligently and differently than we do now.
In Texas, the Electric Reliability Council, or ERCOT, is adding renewable energy sources and grid-scale storage at a rapid pace, yet that is only part of the equation. New transmission lines need to be built to deliver the energy where it’s needed, when it’s needed. It is also about when we use it. Potential to adapt and shift energy demand lies within our homes, just like the rhythmic motions of dancers responding to the changing tempo of music.
In the complex dance of climate action, homeowners, businesses and governments each have a unique step to perform. Homeowners, for example, can move in harmony with the grid’s beat, making energy-saving adjustments during peak hours. Simple actions such as delaying the use of energy-heavy appliances until off-peak hours or adjusting the thermostat during peak demand times is a great start.
Businesses have the opportunity to choreograph innovative technologies that maximize demand flexibility and response. Investing in the development and deployment of smart devices and energy management systems will allow homes to better sync with the grid’s rhythm, maximizing renewable energy usage and minimizing peak load demands.
Government has the important role of composing policies that facilitate and incentivize these actions. For instance, implementing time-of-use electricity pricing can incentivize homeowners to shift their usage to off-peak hours, thereby balancing grid load and reducing stress on our energy systems. Yet, Texas lawmakers appear out of step. The recent legislative session fell short of supporting essential energy reforms, neglecting the potential of renewables.
We have the opportunity to transition our homes. It’s about us actively choosing to participate in programs that balance the energy needs of our grid. This might even involve storing some of that energy for later use, like saving the grand finale for just the right moment.
Whatever our respective roles, the dance toward aligning our energy consumption patterns with grid decarbonization through demand flexibility and response means a cleaner, more sustainable energy future. However, the choreography isn’t without its complexities. Consider the potential hiccup of all our smart thermostats, batteries or electric vehicles stepping forward in unison to grid conditions, risking a concentrated peak load and possible stumble of grid instability or blackouts. It’s clear our solution lies in large-scale load coordination — a master choreographer managing the energy consumption patterns across and within neighborhoods.
It also creates business opportunities for utilities or third-party aggregators to create products enabling efficient load coordination. Utilities or third-party aggregators, like talented dance instructors, can create solutions enabling efficient load coordination. By collaborating with homeowners and leveraging advanced technologies, these entities can choreograph the energy dance and generate savings. Indeed, a recent report shows that avoiding the construction of new power plants and unlocking demand flexibility instead could net savings of up to $35 billion nationwide.
We must ensure equitable progress. We need to embrace the spirit of individual action and consider how our homes and businesses can contribute to the grid rather than simply relying on it. If more of us do that, we can transform our energy dance into a harmonious blend of supply and demand, turning our homes into active partners in a sustainable, renewable energy future.
