- kWh estimator: To estimate your electricity use, multiply the wattage of each appliance by the hours used each day to get daily watt‑hours, divide by 1,000 to convert to kilowatt‑hours, then multiply by 30 for a monthly estimate. Online kWh calculators such as SaveOnEnergy’s estimator simplify this process and help you forecast bills.
- DOE appliance & lighting calculators: The U.S. Department of Energy offers calculators to estimate the energy consumption of appliances, lighting, HVAC systems and other equipment. These tools help identify which systems are driving costs and evaluate the impact of upgrades or replacements.
- Energy Star Portfolio Manager: This free tool from the EPA lets businesses track and benchmark energy and water consumption across buildings, compare to peers and set efficiency targets. It’s widely used for portfolio energy management.
- EIA price data: The U.S. Energy Information Administration publishes average retail electricity prices by state and sector. Use this data to benchmark what you pay against state and national averages and inform contract negotiations.
- Rebate & incentive databases: Websites like DSIREUSA and your local utility’s rebate listings show incentives for energy‑efficient upgrades, renewable energy projects and demand response programs. These can offset upfront costs and shorten payback periods.
- Energy management systems: Dedicated energy management software and hardware provide real‑time monitoring of demand, load and power quality. They can help identify spikes, shift usage to off‑peak times and reduce demand charges.
Using these resources can give you the data you need to select the right electricity plan, manage consumption and uncover opportunities for savings.
