Energica will be the exclusive bike supplier for the 2019 FIM Enel MotoE World Cup

Electric-bike people say the improvements in range and performance of electrics have come mainly from expanding knowledge of how best to manage the limited energy that batteries do contain. This is similar to the fuel-economy research that cost MotoGP teams serious R&D money during the 20-liter fuel-limit period. Where on the track and under which circumstances can engine power make the most economical contribution to a fast lap?
Highly efficient (98 percent) electric motors have existed for 100 years. The present power supplies and controllers are likewise excellent, leaving the battery itself as the limiting factor. All around the world, hundreds of laboratories both commercial and academic are constantly exploring battery problems, seeking to better combine the desired properties—energy density, cost, cycle life, rapid charge/discharge, safety. Li-ion was conceived in 1975–’76, commercialized by Sony in 1992, and has since received a quarter century of intensive development.
Another question is, do electric vehicles offer benefit in reducing global emissions of greenhouse gases? There is no question that an all-electric vehicle fleet would benefit urban air quality (zero emissions at the point of energy use) but at global scale we must consider where electricity comes from and at what efficiency. During 2016 these were the sources/percentages of US electric power:
- Natural gas 34.0
- Coal 30.4
- Nuclear 20.0
- Hydroelectric 7.0
- Wind 5.6
- Solar 0.9
- Other 2.1
Wind- and solar-power generation are increasing. Wind supplied 4.1 percent in 2014, 4.7 in ’15, and 5.6 in ’16. Solar has risen above 1 percent during 2017. In 1996, 87 percent of US electricity was generated from fuels sourced underground, but 20 years later that percentage had fallen to 84.4.
When you multiply together the many efficiencies that exist from powerplant to electric-vehicle propulsion, you find that for power from thermal plants (coal, nuclear) overall efficiency is around 20 percent. With power from the best combined-cycle natural gas plants (gas turbine) now coming on line in Europe it can be as high as 33 percent, but for the US’s present mix of simple cycle and more modern natural gas plants the number is more like 25 percent.
Germany, often cited as a powerhouse of renewable energy because of its sometimes-remarkable daily peak wind/solar generation figures, still on annual average relies on low-grade domestic coal for 40 percent of its electricity.
Futurists naturally yearn for perfection by Friday at the latest, but infrastructure change is slow, requiring years of financial investment. In the present economy investors are cautious and they act only to earn a profit.
This makes electric-bike racing just a droplet in the hoped-for tide of change, but we can hope it has interesting and valuable things to teach us.
