When it comes to electricity, we often use two important terms: energy use and energy demand. While they might sound similar, they are actually two different things. Since electricity is primarily invisible, it can often be difficult to visual these concepts. Let’s break it down with a visual analogy: water coming out of a faucet.
Energy Use: The Volume of Water
Think of energy use as the amount of water that flows out of a faucet over time. Just like you measure water in gallons, we measure energy use in kilowatt-hours (kWh). This is the total amount of electricity you consume. For example, if you use a 2,000-watt oven for an hour, it uses 2 kWh.
Energy Demand: The Water Pressure
Now, imagine the pressure of the water coming out of the faucet. This pressure represents energy demand. It’s the rate at which you use electricity at any given moment. High demand is like having more water come out at once, causing a surge in water pressure. Similarly, when you use high demand appliances or turn on several electrical devices at the same time, your energy demand increases.
Why It Matters
Understanding the difference between energy use and energy demand is important for managing electricity efficiently. High energy demand can strain the electrical grid, especially during peak times when many people use a high amount of electricity simultaneously. In the winter, these typically occur on weekday mornings between 6-10 a.m. During the summer, high demand usually occurs on weekday afternoons between 1-6 p.m.
By spreading out your energy use, you can help reduce strain on the grid and help the co-op control costs by reducing peak demand charges. As a not-for-profit organization, when the co-op saves, all our members save.
Tips for Lowering Energy Demand
Managing energy demand is crucial for reducing electricity costs and ensuring a stable power supply. Here are some specific tips to help you lower your energy demand.
Shift energy-intensive tasks: Perform energy-intensive tasks, such as running the dishwasher, doing laundry or using your water heater, during off-peak hours.
Install a programmable thermostat: A programmable thermostat can help you manage your heating and cooling more efficiently. In winter, set it to 1-2 degrees lower when you’re not home and raise it just before you return.
Use timers and smart plugs: Timers and smart plugs can help you control when certain devices are turned on and off. For example, you can set your water heater to turn on only during off-peak hours.
Pre-heat or pre-cool your home: Pre-heat or pre-cool your home before peak demand times. This way, your HVAC system will operate less during peak periods.
Educate your household: Make sure everyone in your household understands the importance of managing energy demand and follows these tips.
By implementing these strategies, you can lower your energy demand, save on electricity costs and contribute to a more stable and efficient power grid.
