Petroleum will not last forever
Petroleum is a limited resource and a vexing source of price spikes, geopolitical instability, and environmental disasters of epic proportions. Petroleum currently fuels 95% of the United States transportation sector, a sector that demands nearly 28% of total energy usage. Globally, demand for personal transportation is increasing while reserves are decreasing. Not only is petroleum a diminishing resource, but it is also a significant source of greenhouse gas emissions.
Fortunately, reducing the use of oil for transportation can quickly increase independence and reduce emissions. Tesla vehicles are seminal to developing a cleaner, more independent transportation paradigm.
Clean energy is the future
Reducing the transportation sector's dependence on petroleum means increasing dependence on electricity. As transportation increases its use of the electricity grid, the demand for energy will rise. This demand can be met by bringing online increasingly efficient power plants and renewables. Many countries have committed to decreasing dependence on fossil fuels by increasing their renewable energy portfolios. The United States Federal Government has pledged to reduce greenhouse gas emissions by 28% by 2020. In Europe, renewable energy should account for 20 percent of energy consumption by 2020. Germany alone has more than quadrupled the amount of renewable energy feeding its grid in less than a decade.
Some may argue that electric vehicles simply replace one polluter (petroleum) with another (coal). To use the United States electricity grid as example, Tesla vehicles cut in half the carbon dioxide emissions of its petroleum-burning rivals, despite the fact that about half the grid is powered by coal. We can do better. Over the past five years, United States electricity generation from renewables has increased while coal decreased. As this shift happens, electric vehicles become even cleaner. In California, renewables (13%) contribute more to the grid than coal (12%).
Many Tesla owners around the world take emissions into their own hands. Increasingly, they rely exclusively on solar for their complete energy needs and in doing so, they tread more lightly on the planet. Some utility companies offer their customers the opportunity to buy energy generated exclusively from renewable sources. In both cases, Roadster owners lead a truly emission-free lifestyle.
