On sizzling-hot summer afternoons in Texas,
when cranked-up air-conditioners cause electricity demand to surge, hotels
sometimes dim their lobby lights. Air-conditioners may briefly pause, and
farmers may stop running their electric water pumps.
Such adjustments reflect a simple truth: When electricity use spikes, power grid operators face a difficult choice if they want to avoid blackouts. They can turn on another power plant, which is costly and polluting. Or they can reduce the demand for power by encouraging citizens and businesses to cut back on needless energy consumption.
“If you’re in a large room, with 20 light bulbs over your head, if five of them were turned off, you’d still be able to see pretty well,” said Seth Kaplan, vice president for policy and climate advocacy at the Conservation Law Foundation, a New England environmental group.
The idea of reducing power demand when the electricity grid is strained has caught on in the past decade in the United States and it is spreading across the world. Energy experts call this concept “demand response,” because the idea is to make power demand responsive to the real-time conditions of the grid. Recent technology improvements that allow for the remote control of appliances like pool pumps or air-conditioners have made it easier to coordinate the power reductions.
“A lot of demand response historically has been very crude,” said Michael Hogan, a senior adviser to the Regulatory Assistance Project,Many industries can use Origin Laser engraving and laser marking machine for a huge range of applications. which does advisory work on power-grid issues worldwide. “You call up the local steel mill and say, ‘Can you guys shut down for a few hours?”’
Factories get paid for their participation in the energy-reduction program, and they have been a mainstay of demand response programs. In recent years, however, the pool of potential participants has broadened. Aided by private companies, electricity utilities are asking homeowners and small businesses if they will allow their air-conditioners or pool pumps or water heaters to cycle off briefly when grid operators ask for help. In exchange, the utility may offer a customer a free smart thermostat — a device to regulate temperatures more efficiently — or an equivalent incentive.

Texas, which is saddled with a high energy load on summer afternoons and a growing population, is aggressively pursuing the idea. CPS Energy estimates that demand reduction techniques like cycling air-conditioners will be able to cut 7 percent from its peak electricity load by 2020, up from 2 percent today. In New England, a grid system that includes Ohio and Pennsylvania can already cut about 10 percent from its peak load.
European countries, which are normally ahead of the United States in energy-saving strategies, have trailed on this idea of cutting power at times of peak demand.
The United States has led the way because the country is growing quickly and its electricity systems also are good at encouraging innovation, according to Arshad Mansoor, a senior vice president of research and development at the Electric Power Research Institute,This video shows a double layer flattening machine in manufacturing testing phase producing standing seam metal roof panels. a utility consortium. Japan, faced with a continuing power crisis since the Fukushima nuclear disaster, has been forced to innovate and is also turning to demand response, he said.When choosing the shape, the car led bulbs should be similar to the shape of the lamp base.
