E.To reduce smog, a state mandates that all state employees on state business must drive electric vehicles instead of gasoline- powered vehicles; the energy used by these electric cars comes from coal- and oil-burning power plants that emit carbon dioxide. 点击查看答案 第7题 听力原文: One...
Learn more about regen braking in our how to drive an electric car guide. Hybrids offer better fuel economy and emit less CO2 than a traditional gas-powered car, but they don’t reach the zero emissions of an all-electric. However, they do feature stop and start technology for less ...
Humanity has a shrinking window to drastically reduce greenhouse gas emissions, yet climate action is still lacking on both individual and policy levels. We argue that this is because behavioral interventions have largely neglected the basic principles of operant conditioning as one set of tools to p...

LCAs havefoundthat electric cars emit less carbon dioxide (CO2) than standard cars, butcarbon dioxideis an organic, colorless, non-carcinogenic gas that has no toxic effects on humans until concentrations exceed at least 6 times the level in Earth’s atmosphere. Thus, CO2 has no bearing ...
“Electric cars have a very dirty secret The technological flaws of battery-powered vehicles have not gone away. This dirty secret was confirmed by a recent piece of research by Volvo. Researchers studied the full lifetime CO2 emissions, from resource extraction...
X-ray proportional counters work by using a gas to convert the energy from the ionizing radiation into an electrical signal. This signal can then be amplified and used to trigger an alarm or display a reading on a meter. There are many different uses for x-ray proportional counters. They ...
U.S. cities are starting to make the transition as well. In Columbus, Ohio, the Yellow Cab fleet has 20 electric cars (out of 170 total). Meanwhile, New York City is trying to reduce the carbon that taxis emit each year. The city released aroad mapin 2014 to make o...
The article discusses the method of diagnosis of wheel castings used in passenger cars. The aim of the conducted tests was to perform a wheel rim diagnostics in the scope of correctness: chemical composition, mechanical properties, wheel rim hardness in specific areas. The main research goal was...
Lithiumis one of the primary components of the batteries used to build electric cars. Lithium-ion batteries have a higher capacity than batteries with other metals that can be used in mass production, and they can be charged many times before they degrade. The use of lithium in auto manufactu...
