ENERGY STAR certified appliances

What Makes A Home Energy Efficient?

A home is considered energy efficient when it uses less energy to perform the same tasks as a conventional home. This includes improved insulation, energy-efficient appliances, better HVAC systems, and the utilization of renewable energy resources. The key components are:

  1. Proper insulation to minimize heat loss or gain.
  2. Efficient windows that reduce energy wastage.
  3. ENERGY STAR appliances that consume less energy.
  4. Smart thermostats for precise temperature control.

Energy Efficient Home Improvements

Energy-Efficient Lighting

Switching to energy-efficient lighting, such as LED bulbs, can save up to 90% of the energy used by traditional incandescent bulbs. LEDs have a longer lifespan, reducing replacement costs over time.

Sealing & Insulation

Proper sealing and insulation can significantly reduce heating and cooling costs. This involves sealing gaps and cracks and adding insulation to walls, attics, and basements to maintain a stable indoor temperature.

Better Thermostat

Installing a smart or programmable thermostat allows you to optimize your home’s temperature settings, which can save up to 30% on energy bills. These thermostats learn your schedule and adjust temperatures accordingly.

Energy-Efficient Windows

Replacing old windows with energy-efficient ones can save 25% to 50% on heating and cooling costs. These windows have better insulation properties, reducing energy transfer.

Efficient Heating & Cooling

Investing in high-efficiency heating and cooling systems can lead to considerable savings. Below is a table of different options and their associated costs:

Efficient Heating & Cooling Options and Costs
High efficiency AC unit cost
HVAC zoning system cost
Ductless mini-split AC cost

Additional Improvements:

Efficient Water Heaters

Replacing a conventional water heater with a tankless or solar option can save energy and reduce utility bills. Tankless water heaters heat water on demand, avoiding the energy waste associated with keeping a tank of water hot.

ENERGY STAR Appliances

Opting for ENERGY STAR-certified appliances ensures better energy efficiency. These appliances are rated by the U.S. Environmental Protection Agency to meet strict energy performance standards, leading to significant savings over time.

Bathroom Efficiency

Updating bathroom fixtures, such as low-flow toilets and showerheads, can reduce water and energy usage. Efficient fixtures use less water without compromising performance, leading to lower utility bills.

Efficient Roofing

Installing energy-efficient roofing materials, such as cool roofs, can reduce the amount of heat absorbed by your home and lower cooling costs. These materials reflect more sunlight and absorb less heat.

Electrical Wiring

Upgrading your home’s electrical wiring can improve efficiency and safety. Modern wiring systems reduce energy loss and support sophisticated energy management systems.

Renewable Energy Systems

Adopting renewable energy systems is an excellent way to enhance your home’s energy efficiency and reduce your carbon footprint. Here are some options and their average costs:

Renewable Energy Updates and Costs
Solar panel cost
Solar roof cost
Solar battery storage system cost
Solar pool heater cost
Solar water heater cost
Portable solar generator cost
Wind turbine cost

Home Energy Efficiency FAQs


ENERGY STAR is a program run by the U.S. Environmental Protection Agency and the U.S. Department of Energy that helps consumers identify energy-efficient products. Appliances with the ENERGY STAR label meet strict energy efficiency guidelines and can significantly reduce energy costs.

What Appliances Or Systems Waste The Most Electricity?

Large appliances such as refrigerators, washing machines, and dryers often consume the most electricity. Heating and cooling systems, especially older, inefficient models, also contribute to high energy consumption. Identifying and upgrading these systems can lead to substantial savings.

Does Unplugging Devices And Appliances Save Money?

Yes, unplugging devices and appliances when they are not in use can save money. Many electronics draw power even when turned off, a phenomenon known as “phantom load.” Unplugging or using power strips can help reduce this wasted energy.

Getting Estimates For Energy-Saving Home Improvements

When planning energy-efficient upgrades, it’s essential to obtain multiple estimates to ensure you get the best value for your investment. Consulting with professionals can help you understand the potential savings and costs involved.

Questions To Ask An Energy-Efficient Home Improvement Contractor

  • What type of energy-efficient upgrades do you specialize in?
  • Can you provide references or case studies from previous projects?
  • What certifications do you hold for energy-efficient installations?
  • How do you determine the potential energy savings for each upgrade?
  • What kind of warranties or guarantees do you offer on your work and products?

Improving your home’s energy efficiency is a wise investment that can lead to significant cost savings and environmental benefits. By understanding the various upgrades available and consulting with qualified professionals, you can create an energy-efficient home tailored to your needs.
