Reducing Waste
Energy Efficiency
Helping the world use less energy to deliver growth with reduced waste, lower costs, and less pollution for all
A system built on waste
Nearly two-thirds of today’s global energy is lost before it delivers value — through inefficiencies in production, transport, and end use. Waste, in the form of pollution, unused heat, and other losses costs trillions each year, and harms growth, public health, and the environment.
$4.6 trillion
Value of energy wasted by current systems, or about 5% of worldwide GDP.
$1,000+
Annual savings delivered to every American since 2000 thanks to efficiency gains in lighting, appliances, and other advances
>70%
Portion of every gallon of gas that is lost in a conventional car as heat, friction, pollution, and other waste. Electric vehicles lose around 10% of each unit of energy input.
Understanding Efficiency
Improving the efficiency of our energy system will mean replacing fossil fuel technologies with rapidly scaling renewable energy and electrification solutions, which are often two to four times more efficient. Delivering fully on the promise of energy efficiency means creating more efficient products, buildings, and factories, and broader systems — such as cities, industrial hubs, and supply chains.
Working with local governments, manufacturers, fleets, industry, and communities, RMI’s experts focus on electrification and other innovations to build a cleaner, more affordable transportation system for tomorrow.
Working with utilities, policymakers, manufacturers, industry groups, and community organizations, RMI experts are at the forefront of tackling unique buildings challenges — from retrofit solutions that reduce installation and operating costs, to design incentives that make efficient, demand-flexible electrification the intuitive choice.
RMI partners with heavy industry to unlock efficiency, innovation, and competitive advantage.
RMI designs system-level solutions to provide low-cost, reliable electricity to households, businesses, and communities around the world.

How Big Is the Energy Efficiency Resource?
“…most traditional analysts and deployers of energy efficiency see and exploit only a modest fraction of the worthwhile efficiency resource, saving less and paying more than they should. Yet empirically, modern energy efficiency is, and shows every sign of durably remaining, an expanding-quantity, declining-cost resource.”
