It has been a fact of life for quite some time now that the world’s oil deposits are finite and will eventually dry up. That is why the energy sector should already have replacement technologies in the „pipeline” for when this happens, so that we have alternative energy sources to fall back on. The automobile industry is no exception and there are technologies that may prove to save us from oil dependency.
Many new vehicle technologies have the goal of steering automobiles away from a dependence on fossil fuels. One vision is an all-electric vehicle (EV) that uses no gasoline or diesel fuel and does not emit any carbon dioxide. But affordable and reliable EVs will require advances to be made in energy storage. Currently, batteries that store enough electricity to give a vehicle acceptable driving range are costly, bulky, and heavy. However, technology may provide new options. For instance, recent milestones in nanotechnology, applied to the lithium-ion battery, may permit significantly more energy to be stored in a smaller, lighter battery pack.
PHEVs, which is an acronym for plug-in hybrid electric vehicles, have conventional gasoline engines as well as batteries that can supply enough energy to travel 10 to 40 miles, depending on the kind of batteries used. The compromise may secure a significant place in the market sooner than later, the fact being that according to, for example, Toyota sales figures, one in four Aurises sold is a hybrid. They run on electric power until the batteries are discharged, then switch to gasoline for additional range. Alternatively, they use the electric engine for the most fuel-intensive processes, such as putting the car into motion, or low-effort processes, such as coasting.
EV and PHEV batteries are recharged on the fly by using the car’s thermal and kinetic energy or by plugging them into an electricity source while the vehicle is parked. This provides the immediate benefit of shifting some transportation energy demand from onboard petroleum-based fuels to the electrical grid. However, carbon dioxide emissions would not decline proportionally because half of the electricity used to recharge the vehicle’s batteries is produced at coal-based power plants.

There are two groups of words that are very easily confused in English – the first describes things and people (i.e. adjectives), and the second second describes actions (i.e. adverbs). The former answers the question „what kind?”, the latter „how?”. You’ve seen several examples of both groups in the text.
Choose the best option.
1. We need to come up with alternatively / alternative energy sources before oil runs out.
2. I’m not rally interested in currently / current events, there’s too much drama on the news.
3. There’s been a significantly / significant progress in the area of electric vehicles.
4. Eventually / eventual, we will have to replace oil with something else to burn.
5. Your salary should be proportionately / proportionate to your knowledge and experience.
6. There are computers that have no conventionally / conventional hard drive, they store everything, including the operating system, in an online cloud.
