Batteries Included - A Future Of Green Silence

To the surprise of many people, the concept of vehicles powered by electricity is not a new one. Although there has been much widespread publicity in recent years about the new age of greener and more environmentally friendly vehicles powered by electricity rather than gas, the first successful electric vehicles were actually being developed nearly two hundred years ago, back in the 1830s. Robert Anderson in Scotland created a successful electric carriage capable of speeds up to 65 miles per hour, and by the 1900s electric cars were more popular than gas powered ones, and were certainly quieter, cleaner and easier to start.
Today the average person may still think of electric cars as being either a very new idea which may or may not catch on, or imagine that all electric cars are like milk floats or golf carts - rickety old vehicles which are so slow that the average child on a scooter can beat them into town. However, with cars like the Tesla Roadster overtaking a Mercedes SL550 with comfort, and leaving the poor old gas guzzling Ferrari Spider standing at the lights wondering what happened, popular opinion and understanding is changing. With a top speed of 130 miles per hour and a round trip of 250 miles easily manageable on a three hour charge, this is hardly a golf cart.
Often it is forgotten or ignored that there is another side to the use of electric vehicles to be kinder to the environment. It’s not all about the smoke and fumes that will be saved, but also the noise factor. Electric cars are almost silent, the only sound from within the sporty models being a vague impression of having a hairdryer in the boot. Noise pollution is a forgotten attribute of gas powered cars, but imagine a world of near silence. Some people have expressed concerns that with nippy little cars silently dashing about that children and the elderly may find it difficult to anticipate or seen these coming, and that road calming measures or extra noise making speaker need to be fitted.
It isn’t only the fact that those who buy and use electric powered vehicles can sleep easy at night knowing that they are doing their bit for the environment. To really be appealing to the average consumer it has to make financial sense as well as environmental sense, and in this regard electric vehicles can score very highly. For example, for a mere fraction of the cost of the average car you can purchase a G-Wiz, which sits snugly in the lowest bracket for road insurance, and is also exempt from road tax. With two hundred recharging stations across the UK, keeping it running is easy, and if you live in London there’s a huge advantage because you are allowed to park for free, as well as being exempt from the congestion charges. This alone can represent a saving of over 5,000 per year, which is more than the cost of the car!
On a much larger scale, one country has taken the gigantic step forward and proposed a strategy to entirely eliminate their need for oil to support their road traffic within ten years. Israel has recently unveiled its Project Better Place which is a long term plan to replace oil based gas guzzling vehicles with electric ones, with an estimated completion date of within ten years. The country already has half a million stations which support the re-charging of electric vehicles, and with the average distance capable of being travelled between charges more than ample to enable a vehicle to travel between any two points within the country without the need to stop, it is both an ambitious project but one which looks as though it could very well set a high standard for the rest of the world. The plans include introducing electric vehicle distribution in a similar way to mobile phones, with companies giving the cars away free whilst users simply pay for the cost to use or charge the car, doing so either on contract with unlimited usage, or on a pay-as-you-drive basis.
As with any new development, the ultimate success relies heavily on consumer demand, and companies piloting electric vehicle schemes are trying hard to win that consumer demand and interest. With electric vehicles being showcased in Hollywood, such as the Lexus driven by Tom Cruise in Minority Report, people are starting to realise that the future isn’t a world full of milk floats, but of slick and powerful cars that anyone would be proud to drive. With the US home to nearly eight million electric vehicles, consumer demand is very much a voice loud enough to have caught the ears of politicians.
Many people have raised concerns regarding the apparent green option which electric vehicles represent, citing the fact that they still need to be charged, and that this electricity comes from power companies burning fossil fuels. This is not entirely true, as there are an increasing number of companies and facilities generating green energy, either partly or in full. However, even if the power does come from burning fossil fuels, there is still an advantage, since it’s all about the conversion ratio of fuel to energy. Burning fossil fuel in a car is highly inefficient, whereas using fossil fuel to generate electricity which is used for electric vehicles is a far more efficient use of that energy, and therefore will result in far less fossil fuel being required.
Imagine a future where we can all drive around in almost virtual silence, with no fumes, no smoke, and even if we get stuck in traffic jams or sit stationery at lights, we don’t have to worry about burning fuel unnecessarily. Some people have expressed concern that in this seemingly idyllic future the power companies would fail because at night, when we all plugged in our cars to recharge, we’d overload the grid. In fact, at night this is when the grid is used far less, and estimates have been made that if we all switched to electric cars, the power grid would be able to work at almost half the capacity it does now. Perhaps we can envisage a future where we come home, plug our car into the fuel cells charged through the day by the solar panels on our roof, and sleep with a clean, and green, conscience.
