بحث عن الطاقه بالانجليزي.

Early man relied on fire for the luxuries of light, heat, and cooking. Today, we take all these luxuries for granted. At the flick of a switch, a push of a button or the turn of a knob, we can have instant power. Electricity plays a huge part in our everyday lives. Whether it is at home, school, the local shopping center, or our workplace, our daily routines rely heavily on the use of electricity. From the time we wake up in the morning until we hit the pillow at night, our daily life is dependent on electricity. The alarm we have to turn off each morning runs on electricity. The light in our bedroom, the hot shower we take before breakfast, Dad’s electric razor. All these things need electricity in order to function. Even our first meal of the day is heavily dependent on electricity. The fridge that keeps all our food cool and fresh needs electricity to run or the grill that cooks your bacon and eggs also needs power to operate. This power generally (unless you have gas stove) comes from electricity. Electricity not only plays a big part in our daily lives at home, but it is extremely important for all the things that go on in the world around us in our modern life, such as industry that we depend on, communication as in form of radio, television, e-mail, the Internet, etc. Transport is another aspect of our daily life that depends on electricity to some degree.

Electricity has changed cooking in a very dramatic way. From caveman days to the 19th century, people had to cook meat with fire. Then came electric stoves, electric ovens, toasters, and microwaves. In the past, bakers depended on manual mixers to make dough because they didn’t have cooking appliances. Ovens relied on firewood instead of electricity, and the wood had to be chopped, hauled, and stacked on a regular basis. Even if you wanted to boil water, you had to get a fire going. Electricity changed all that, making food preparation much more convenient. Finnish scientists are even working on a way to create food directly out of electricity.

Electric trains are the most popular form of electric transportation, but there are now also electric bikes, buses, rickshaws, cars, trucks, motorcycles, scooters, and airplanes. Electric boats have been around since the 1880s, but they fell out of fashion when the gas-powered outbound motor showed up in the 1920s.
