There are a variety of reasons why you may like a hybrid car. You might like a hybrid car in order to cut your ever increasing petrol bill; in order to reduce your personal impact on the environment or you might just want the kudos of driving a car that is at the forefront of technology. Obviously, it could be for a mixture of all three reasons too.

Hybrid cars have been around for around ten years and so the technology is fairly well advanced. The thing to bear in mind is that hybrids are not performance cars in the traditional sense of the word. In the perspective of cars, the word ‘performance’ normally means ‘high speed’, but hybrid cars are performance cars because they save more than eight percent on the fuel bill.

They create this saving by in essence using two engines. The one engine is a conventional internal combustion engine (ICE) and the other is an electric motor. Both engines distribute their power through the same mechanical means to the wheels. The ICE generates electricity and delivers it to a battery, like any car does, however, a hybrid car can use this battery power to drive the car as well.

The electricity is generated by alternators and the braking system. Regenerative braking supplies a large amount of power to the batteries. In fact, so much so that under regular driving conditions, the batteries do not have to be charged from the national grid.

The ‘early’ hybrids used the electric motor just as an ‘assist’. In other words, while the petrol engine would usually require to be revved up to produce enough power to overtake or go up hill, the electric motor would jump in to assist it, thereby saving fuel, but the petrol engine is effectively running all the time. This a form of halfway hybrid. The Honda Insight was one of these.

However, a full hybrid will use one or the other or both of the engines, depending on how its computer best interprets the power needs of the driving conditions. The driver has no decisions to take, engines are turned on and off automatically and seamlessly by the car’s on board computer. Examples of this sort of full hybrid are the Toyota Prius and the Ford Escape Hybrid.

Although most individuals think of hybrids as new technology, the first hybrid car was made over a hundred years ago. Modern hybrids are about ten years old and the technology is improving rapidly. However, what actually has to happen now for hybrids to make a real impact on the amount of oil that the West consumes is for the prices to come down.

And I mean really come down a lot. Hybrid cars are far too costly for the average driver. If manufacturers reduced the price of the cars, more individuals would buy one which would stimulate the economy and aid the balance of payments deficit to say nothing of the effect of burning less fossil fuel would have on the environment.

A new kind of hybrid has entered the English language. Not so long ago, if you heard a fragment of conversation containing the word ‘hybrid’ you would have assumed that it either referred to a rose, as in ‘F1 Hybrid’ or possibly a wolf-dog variety. However, nowadays, someone mentioning the word ‘hybrid’ is more likely to be referring to a vehicle.

A new sort of car that has two engines and burns far less petrol or diesel than its antecedents because it relies on modern technology. The idea of a hybrid car is not new at all. One of the first cars, well over a hundred years ago was a hybrid. In fact, that ancient hybrid car also used petrol and electricity from batteries.

Contemporary hybrid vehicles also create use of oil derivatives and electricity stored in batteries as sources of power. In essence, a hybrid car will use its petrol engine when the driver needs power, for instance whilst overtaking or going up hill, but it will automatically switch to the electric motor whilst the car is at a cruising speed or creeping through inner city traffic.

The switch from one power source to the other is automatic and seamless. The driver may be aware of the change, but does not have to initiate that switch or even approve it.

Most hybrid cars will switch themselves off when the car comes to a halt and will start up again whilst the accelerator is depressed. This one feature alone saves a lot of fuel. In traffic, the car is probably using its battery-powered electric motor anyway, so it is very straightforward to stop and start it.

A hybrid car can be plugged into the national electricity grid to recharge its batteries, which might be necessary occasionally if the car is locked in traffic for a substantial part of the week. However, if you drive on long runs and in the city, that is give your hybrid car a balanced usage, the car will keep the batteries recharged by itself – usually by the use of alternators and the braking system.

The hopes of governments, environmentalists and drivers are being pinned on the more widespread use of hybrid cars and here are a couple reasons why:

1) if the fuel efficiency of US cars was raised by one mile per gallon, it would save the total oil produced in the Arctic National Wildlife Refuge over two years.

2) the US would not have to import any oil at all from Kuwait or Iraq, if engine effectiveness was raised by 2.7 mpg

3) if US car fuel efficiency was raised by 7.6%, then they would not have to import any oil from the Gulf at all.

Hybrid cars by and large save more than 7.6% on oil consumption, so the proliferation of hybrid cars and hybrid trucks could resolve the fuel and environmental crises being felt by Western countries and eradicate our dependence on Arab oil.

Maybe you are one of the people who is sick of hearing all about the wonders of solar power. If that’s the case, you probably don’t realize how versatile it can really be. Consider the inexpensive, safe, and super-efficient solar ring. This little device floats on the top of the water in a swimming pool. You hook the rings together and the cover the water’s surface.

They take energy and heat from the sun, and transfer it into the water. They cost very little, heat your pool efficiently, and are very safe. If they are touched they break apart; there is no way to get trapped beneath them or tangled in them.

When was the last time you were out somewhere and your cell phone ran out of charge? Or your laptop started winding down, and there was no outlet handy to charge it back up? If you had solar powered chargers for your cell and laptop, that would not have been an issue. You can even get special cases for laptops that have solar energy cells built in, and you can charge your laptop right in the case.

Another great solar power invention is the solar power attic fan. You can cool your whole attic at very little cost with one of these. The rest of your house will then also be cooler. Better still, this little beauty only takes one solar panel but is super-effective.

If you have one of these fans, your air conditioning will be more efficient and also therefore less expensive. Your air conditioning unit won’t have to work to cool the attic.

You can run nearly anything in your house on solar power. It ends up being less expensive too. Maybe now you are seeing how useful and efficient solar systems are.

It costs more at the outset to set up your home with solar power. You have to revamp your electrical system, but you’ll recoup the cost in less than ten years. After that it is all pure savings.

The solar panels aren’t really all that obvious, but if you find the standard ones unattractive or prefer not to have them mounted on your roof, you can opt for the photovoltaic panels that are essentially solar shingles. They blend in well, and work just fine.
