The power factor is the ratio of real to apparent power in a power system. Drawing more current results in a lower power factor. Larger currents require costlier infrastructure to minimize power loss, so consumers with low power factors get charged a higher electricity rate by their utility. [ 23 ]
The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...
Motiv's first major contract was with the city of Chicago to convert 20 garbage trucks to use only electric power, starting work in 2012, with the first truck deployed in the middle of 2014. Motiv estimated that Chicago could prevent the release of 10,000 tons of carbon emissions per year by converting one quarter of its garbage trucks in this ...
The U.S. just lost as much as 15% of its small-batch trucking capacity — and consumers are likely to feel the effects in higher prices as the holiday season rolls around.
The Interstate Highway system (2007) Estimated average annual daily truck traffic for Interstate and major US Highways (1998). Components of diesel exhaust were confirmed as an animal carcinogen in 1988 by the National Institute for Occupational Safety and Health, and by 2002, the U.S. Environmental Protection Agency (EPA) considered it "likely to be carcinogenic to humans".

This is around 1 ⁄ 5 (20%) of what is needed to power a standard upright bicycle without aerodynamic cladding at same speed, and 1 ⁄ 50 (2%) of that which is consumed by an average fossil fuel or electric car (the velomobile efficiency corresponds to 4700 miles per US gallon, 2000 km/L, or 0.05 L/100 km).
