However, since the last IEA CHP / DHC Country Scorecard, progress has been relatively slow — CHP capacity as a share of total
national electricity generation capacity has remained stagnant, and some hurdles still exist.

Together with our partners, we work to add new
generation capacity, connect homes, hospitals and businesses to the
electricity grid and deliver power to communities who live beyond the
national grid,» remarked Mr. Hendrix.
As of March, according to USAID figures, Power Africa has helped close deals accounting for 4,100 MW of
electricity in places like Rwanda, where East Africa's largest solar array began sending 8.5 MW of
electricity to the
national grid late last year, boosting the country's
electricity generation capacity by 6 percent.
According to the
National Energy Renewable Laboratory 2013Databook, renewable
electricity grew to nearly 15 % of totalinstalled
capacity and 13 % of total
electricity generation in theUnited Statesin 2013.
More importantly, however, making more gas
generation capacity available is only a short - term fix and does not seriously address the changes needed to maintain, in the words of the
National Electricity Objective, a secure, reliable and affordable supply of e

But he wholly fails to explain what the implications of the variability problem is (the need for overbuild of
generation capacity and expensive / unfeasible large - scale energy storage), nor whether, if an effort is made to deal practically with these problems in real
national electricity grids, the «increasingly cheaper» renewables will ever become cheap enough (when all relevant real - world factors are considered) and reliable enough (without natural gas «backup»), to actually substitute for and displace fossil fuels (or nuclear) at the scale required.
According to the authors, the U.S.'s spare nighttime
electricity capacity could power a large fleet of PHEVs; since they require about 10 hours of nightly charging, Joe Sullivan of the Argonne
National Laboratory, one of the authors, nighttime
electricity could allow PHEVs to replace up to 34 % of today's light - duty fleet - and only consume 13 % of the fuel used nationally for
electricity generation in the process.Michael Kintner - Meyer of the Pacific Northwest
National Laboratory - in a separate study - found that 43 % of the fleet could be replaced by PHEVs with existing nighttime
capacity.
