Buying green
Investing in alternative fuel vehicles is not a no-brainer. The decision to buy a green car remains largely an ecological and political one, although there are some tangible advantages.The current popular and simplified reason to buy a car that emits [link widoczny dla zalogowanych] less pollution is to prevent global climate change. However, efforts to clean up automotive emissions started as an attempt to address public health concerns by reducing smog. Gasoline-burning internal combustion engines release hydrocarbons, nitrogen oxide, carbon monoxide, and carbon dioxide into the atmosphere.
Hydrocarbons and nitrogen oxide contribute to smog, while carbon monoxide is a poison in its own right. Most current automotive emissions controls are aimed at curbing these pollutants.Nitrogen oxide and carbon dioxide, specifically, contribute to global climate change. Currently, there are no laws limiting carbon dioxide emissions from cars, although California is attempting to implement regulations. For every gallon of [link widoczny dla zalogowanych] gasoline burned, 19.6 pounds of carbon dioxide enter the atmosphere. Absent vehicle pollution controls, consumer choices are Americans' only tool for decreasing these automobile-generated carbon dioxide emissions.
For some, green cars offer a tangible benefit: lower or no costs at the pump. Because there is a direct relationship between fuel economy and carbon dioxide emissions, a car that produces less carbon dioxide will cost less to fill up. Hybrid cars used to cost a big more than their gasoline equivalents, but that discrepancy has changed. The Toyota Prius, which gets 50 mpg, starts at $22,[link widoczny dla zalogowanych],000. Lincoln offers its MKZ model with gasoline or hybrid powertrains for the same price. Depending on electricity rates, electric cars can cost substantially less to charge per mile than a gasoline car, and at the [link widoczny dla zalogowanych] same time have zero tailpipe emissions. In this guide, we cover the current car options for people who want to reduce greenhouse gas and smog emissions, along with some experimental technologies
