The Future of Energy: New Infographic Shows Home of the Future

by Bob Shively, Enerdynamics President and Lead Instructor

 

Few would argue that the electric industry is in a period of transition. And that the electric transmission and distribution systems just 10 years from now will be profoundly different from what we know today. As the Electric Power Research Institute (EPRI) states in its report titled The Integrated Grid:

 

“The role and operation of the U.S. electric power system are undergoing profound changes driven by the spread of distributed energy resources (DER).”

 

Such changes will enable the residential energy consumer to become a “prosumer,” who is both a provider and a consumer of grid services. In Enerdynamics’ latest infographic, the House of the Future, we show various elements that will likely be integrated into new homes and retrofit into existing homes.

One key aspect of powering future homes is using energy-efficient technologies that reduce overall energy usage. These include:

  • appliances and lighting that are highly efficient
  • a super-insulated shell and energy-efficient windows
  • geothermal heating and cooling that use thermal energy from the earth to efficiently heat and cool a home
  • a smart thermostat that keeps a home at the optimum temperature determined by the occupant
  • a home combined heat and power (CHP) system that generates electricity and provides heat for hot water and/or space heating

While a single home will likely not include all of these elements, a mix of just some of them will significantly minimize the amount of energy required to meet desired lifestyle demands. 

 

Once a resident has reduced his or her needs to buy energy services from the grid, the next investment may be in technologies that lower energy costs (or even make them go negative so that homeowners are making money!). This may be achieved by shifting electric demand to times when power is the cheapest and/or by selling electricity back to the grid. This is what turns a consumer into a prosumer. Technologies that facilitate this change include:

  • smart appliances; adaptive lighting; a smart thermostat; a controllable water heater; and an electric vehicle with a battery — all of these allow consumers to time shift their electric usage
  • The previously mentioned CHP system, which provides capacity and electricity
  • A solar array that can also provide capacity and electricity
  • A home battery that can provide capacity, electricity, and regulation services and may also allow the homeowner to time shift use of power bought from the grid or generated by a CHP system or solar array

Those who take advantage of these technologies' benefits will want to remain connected to the distribution utility to get the economic benefit of selling these services. This requires a smart meter and a smart inverter that converts the power generated or the electricity discharged from batteries to the level of power quality needed for the distribution system. 

 

All these components won’t run and optimize themselves alone, so a home energy management system (HEMS) is required to manage it all. HEMS users will simply use the convenient home energy app provided by their energy services provider (Google, Facebook, cable/internet provider, electric utility or energy retailer?) to set preferences and the system will then run itself.  Such efforts should result in a reduced energy bill at the end of every month.

 

Sound futuristic? All of these technologies are available today. But to fully integrate them as described above there must be changes to the electric utility model as well as innovative service providers who pull it all together. In some states around the U.S. and countries around the world, this future is not too far away.
