By 2050, the U.S. can phase out its use of oil, coal and nuclear energy by relying on energy efficiency to reduce its energy needs, and meeting remaining the energy requirements with renewables and natural gas.
In Reinventing Fire
, Rocky Mountain Institute investigates the implications of four radically different future electricity scenarios - from a “business-as-usual” case to a network of intelligent microgrids powered largely by distributed renewables.
Premium-efficiency motors are normally assumed to cost more because they use more and better copper and iron. Yet analysis of all models on the 2010 U.S. market, in this case for 250 hp (TEFC, NEMA Type B) shows this is untrue despite standards’ having knocked the least efficient models off the market.
Rocky Mountain Institute’s four scenarios for the future U.S. electricity system ( detailed here
) all have very different requirements for an expanded transmission infrastructure.
The improved efficiency in commercial and residential buildings from implementing Reinventing Fire creates new jobs in the efficiency segment of the buildings sector. In addition, the resulting energy savings increase building owners’ disposable income and induce new jobs in the wider economy as the savings are spent.
RMI analysis predicts a net increase of industrial combined heat and power (CHP) installations of 109 GW, split between traditional cogeneration units and waste heat recovery to electricity systems.
In Reinventing Fire
, the improved efficiency and increased adoption of combined heat and power in the industrial sector create new jobs.
While Rocky Mountain Institute’s four scenarios for the future U.S. electricity system ( detailed here
) have profoundly different resource portfolios, grid structures, environmental impacts, and risk, all the scenarios have very similar overall system costs.
In evaluating the future U.S. electricity system, Rocky Mountain Institute created capital cost projections for fossil and renewable generation technologies through 2050. Many newer technologies, such as concentrated solar power, solar photovoltaics, and battery storage, are projected to have rapidly declining capital costs in the next 40 years.
By Reinventing Fire, the U.S. economy can capture a net present value (2010) saving of $5 trillion. Three fourths of this value is created by changes in the transportation sector and the remaining quarter is driven by changes in the buildings, industry and electricity sectors.
