Installed nuclear capacity initially rose relatively quickly, rising from less than 1 gigawatt (GW) in 1960 to 100 GW in the late 1970s, and 300 GW in the late 1980s. Since the late 1980s worldwide capacity has risen much more slowly, reaching 366 GW in 2005. Between around 1970 and 1990, more than 50 GW of capacity was under construction (peaking at over 150 GW in the late 1970s and early 1980s) — in 2005, around 25 GW of new capacity was planned. More than two-thirds of all nuclear plants ordered after January 1970 were eventually cancelled.  A total of 63 nuclear units were canceled in the USA between 1975 and 1980. 
Moreover, who cares about a hairy army of junk-food loving bears stumbling around the woods of northern Wisconsin? Mainly, the research highlights the degree to which humans cause some wildlife populations to rely on them for food. If killing and scavenging is the bear equivalent to cooking meals, and eating bait is ordering delivery, then bears are ordering in every night of the week, and on some days they’re even ordering lunch. This is normal for some humans, but obviously not for bears, and could have important implications for the way states operate their bating seasons and manage their bear populations.
In the United States, as of early 2010 with a national average electricity rate of US$ per kWh ,  the cost per mile for a plug-in electric vehicle operating in all-electric mode is estimated between $ to $, while the cost per mile of a standard automobile varies between $ to $, considering a gasoline price of $ per gallon.  As petroleum price is expected to increase in the future due to oil production decline and increases in global demand, the cost difference in favor of PEVs is expected to become even more advantageous.
