I think anything by Broan or something energystar.
Depending on what you're referring to, you may have this completely backwards. A motor's efficiency is fairly high. A generator's efficiency at converting chemical/kinetic/mechanical energy to electric energy is at best around 50%.
An electric motor is the best for that job.
Fiberglass is considered the best window frame material for energy efficiency and durability.
Some of the best electric heating systems for homes on the market today include electric furnaces, heat pumps, and electric baseboard heaters. These systems are efficient, reliable, and can provide consistent warmth throughout the home. It is important to consider factors such as energy efficiency, cost, and size when choosing the best electric heating system for your home.
To choose the best bulbs for optimal brightness and energy efficiency, consider LED bulbs as they are energy-efficient and provide bright light. Look for bulbs with high lumens for brightness and low wattage for energy efficiency. Check the Energy Star rating for further assurance of energy efficiency.
When choosing the best electric wall heater for your home, consider the following top features: heating capacity, energy efficiency, safety features, thermostat control, noise level, and installation options.

When choosing electric fans for home use, look for features such as adjustable speed settings, oscillation for better air circulation, energy efficiency, quiet operation, and a remote control for convenience.
Distance and time do not necessarily matter when calculating the efficiency of an electric car motor. Electric cars are best for small distance commutes.
A high-quality rubber weather strip is the best option for under the door to prevent drafts and improve energy efficiency.
The overall best fuel efficiency lies within the new electric vehicles. They are the best because they use two methods of power to move the vehicle, and therefore use less gas when running.
One way to approve the energy efficiency of your home is to go to the Energy Star website. On there, you can access the energy efficiency of your home as compared to other homes. After that, they can tell you how to better seal and insulate and how to heat and cool efficiently.
