Using LED light bulbs reduces energy consumption by up to 80% compared to incandescent bulbs and have a longer lifespan.

Installing a programmable thermostat can save up to 10% a year on heating and cooling by automatically adjusting the temperature during different times of the day.

Appliances with the Energy Star label meet energy efficiency requirements set by the EPA, reducing energy use and utility bills.

Proper insulation in buildings prevents heat loss in winter and heat gain in summer, leading to significant energy savings for heating and cooling.

An energy audit identifies where a home or business can improve energy efficiency, potentially leading to substantial cost savings over time.

Upgrading to energy-efficient windows reduces heat loss in winter and heat gain in summer, which can lower energy bills.

Solar water heaters use solar energy to heat water, reducing the need for electricity or gas, which lowers energy costs and dependency on fossil fuels.

Small-scale wind turbines can generate electricity for homes or businesses, reducing reliance on grid power and lowering electric bills.

Collecting and using rainwater for landscaping and non-potable uses reduces the demand for treated water and can lead to lower water bills.

Low-flow showerheads and faucets reduce water use, which decreases the energy needed for water heating and the volume of wastewater treated.

Smart power strips can cut power to devices when they are in standby mode, reducing 'phantom' energy use and saving electricity.

Upgrading to high-efficiency HVAC systems can significantly reduce energy consumption for heating and cooling and improve indoor comfort.

Replacing old boilers with high-efficiency ones can lead to significant energy and cost savings in buildings that require heating.

Rooftop gardens can insulate buildings, reducing the energy needed for heating in winter and cooling in summer.

Lights with motion sensors automatically turn off when no activity is detected, saving energy by reducing unnecessary lighting.

Double glazed windows consist of two panes of glass with a space between them, which insulates against heat transfer and noise.

Variable speed drives on motors and pumps can adjust speeds according to demand, reducing energy consumption during lower demand periods.

Integrating natural light into building design can reduce the need for artificial lighting and the energy it consumes.

Systems that leverage the constant temperature of the earth can provide efficient heating and cooling for buildings, with minimal energy input.
