Hybrid or electric vehicles (EVs) are vehicles that are powered either by a combination of gasoline and electricity or exclusively by electricity. In addition, hybrids and EVs use efficiency technology to achieve better fuel economy and lower emissions.
Many building owners, parking facilities, and employers—including Google, Bank of America, and Cisco Systems—are installing charging stations in office parking lots to allow employees to charge their cars while at work, thus encouraging adoption of EVs. Even if a charging station is not installed, dedicated parking spaces for EVs can reward employees for using EVs.
If an EV is charged using electricity generated by fossil fuels, significant greenhouse gases are still being emitted; they’re just displaced to another location. The production of a new car also has a significant environmental impact—and hybrids built in other countries have additional impact from being shipped to the US. However, the efficiency of hybrid technology typically leads to overall lower emissions. When considering hybrids or EVs, the environmental impact of the car over the course of its entire life should be evaluated through a lifecycle assessment.
When it comes to EV charging stations, some employers have noted the issue of employees parking at the charge station and leaving their cars there all day, instead of moving them to a parking spot after charging is complete. Charging companies are addressing this issue by offering employers the ability to set up tiered pricing to incentivize people to move their cars after charging is done - e.g. $1/hr for the first 4 hours (most cars take 3-4 hours to charge) and then $5/hr afterwards. Also, new apps sends continuous reminders that charging is done, to remind drivers to move their cars.
