The example of declining solar PV costs
driving growth is highlighted in the EIA data in
Fig. 73. As PV costs have dropped over the past
decade, installations have grown rapidly. While
cost reductions will slow, the impacts will continue to be felt in rapid PV growth in the USA.
PV technology penetration will be driven
largely by on-site installations, especially for
residential use. The EIA projects this to reach
100 GW by 2040 (Fig. 74).
The EIA projects electric vehicles in the USA
to approach 2 million vehicles by 2040, or about
