Solar energy for your home is coming. It can help you as a single home owner. It can help the whole country as well. Whether or not solar energy can save your money depends on many things. Where you live is one factor. The type of home you have is another. Things like insulation present energy coasts, and the type of system you buy are added factors. Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very limited. There is just not enough on hand to meet all our future energy needs. And when Mother Nature says that’s all. The only way we can delay hearing those words is by starting to save energy now and by using other sources, like the sun. We won’t have to worry about the sun’s running out of energy for another several billion years or so. Besides begin an endless source of energy, the use of the sun has other advantages as well. The sun doesn’t offer so many problems as other energy sources. For example, fossil fuel plants add to already high pollution levels. With solar energy, we will still need sources of energy, but we won’t need so much. That means we can cut down on our pollution problems. With all these good points, why don’t we use more solar power? There are many reasons for this. The biggest reason is money. Until now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy. All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being rationed. Solar energy is now in its infancy. It could soon grow to become a major part of our nation’s energy supply.

Nearly 54 million cars and trucks in the United States are equipped with driver side air bags located in the center of the steering wheel. 24 million also have a passenger-side device located in the dashboard. Air bags are designed to protect against sudden, fierce frontal highway impacts. Five years ago evidence of serious air bag injuries began to surface. Drivers in minor fender benders suffered severe eye and ear injuries, broken bones and third degree burns from the force of the inflating bags. In December 1991 the National Highway Traffic Safety Administration(NHTSA)advised parents to avoid putting rear facing infant sets in front of air bags, acknowledging that the force of the explosive bag could harm infants, whose heads were only inches away from the devices. Last October it was determined that all children 12 and under were more susceptible to injury and death than adults; their more fragile bodies were seated lower, increasing the impact of the air bag to the head area. In addition, more children were not properly restrained or were out of position when the air bag inflated. On November 22, 1996, after nearly 60 deaths and thousands of injuries were attributed to the devices, the NHTSA mandated improved labels for all new vehicles, warning of the risk to children under 13. Despite these problems, officials stress the overall effectiveness of these devices. “All in all, air bags work well and are responsible for an 11 percent reduction in driver fatalities. “ says NHTSA Administrator Dr. Ricardo Martinez. “ First and foremost, make sure you’re properly buckled up before getting on the road. “ says Brain O’Neill, president of the Insurance Institute for Highway Safety. Keep in mind how close you sit to an air bag. Push seats as far back as possible, remaining just close enough to control the pedals. Your face and torso should be at least 10 to 12 inches from the steering column. “It’s not a bad idea actually to measure the distance with a ruler to be sure. “ adds O’Neill. Adjustable steering wheels should be pointed toward the chest rather than the head to prevent inflating bag from damaging the face or neck. Also, position hands at nine o’clock and three o’clock on the wheel to keep your arms away from an opening air bag. Pregnant women in particular should keep their abdomen as distant from the air bag as possible. In the final trimester, women should point adjustable steering wheels upward, away from their fetus. Perhaps most important, children 12 and under should always ride in the back seat, buckled up.
