The hidden costs of using an electric bike

Baua Electric

But while you’ll see plenty of people espousing the supposed advantages of electric bikes, it’s important to keep in mind some of the hidden costs of owning and using these two-wheeled electric vehicles. There’s also the reduced wear and tear on your car to consider, plus savings from the reduced car maintenance. of electricity.

Siemens 6 MW direct drive wind turbine in trials

Green Car Congress

Siemens has developed a 6MW wind turbine fitted with an innovative direct drive and therefore not requiring a gearbox. 120 wind turbine should enter series production in 2014. To date, high-output wind turbines have tended to be disproportionately heavy compared to systems of a lower rating.

Porsche, Siemens Energy and partners advance climate-neutral eFuels development; Haru Oni pilot in Chile

Green Car Congress

Electrolyzers will use wind power to produce green hydrogen. The Haru Oni pilot project in Magallanes Province takes advantage of the excellent wind conditions in southern Chile to produce climate-neutral fuel with the aid of green wind power. Enel is a co-funder of the plant, with a focus on wind power and electrolysis.

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

Projects are encouraged to apply concurrent (as opposed to sequential) design methodologies: control co-design, co-design, and designing for operation and maintenance. These methodologies will significantly decrease the levelized cost of energy (LCOE) of the final HKT design. Westergaard Solutions, Inc. University of Virginia.

Different types of motors used in Electric vehicle

Baua Electric

Disadvantages: Limited efficiency, maintenance requirements due to brushes wear. Advantages: More efficient and longer lifespan compared to brushed motors, less maintenance, and higher power density. It reverses the direction of the electric current in the rotor windings, ensuring continuous rotation.
