范文一：太阳能的英语作文
Solar power is the source of life on our planet.
Plants use sunlight to create nutrients and grow. The sun’s daily rays warm the Earth, making it a good place for living things. Scientists have also created solar panels that turn sunlight directly into electricity.
In fact, sunlight causes air movement, creating wind. It also evaporates water, leading to rain. Sunlight even helps our skin produce Vitamin D, which keeps our bones strong.

As life gets better, solar power has become a part of our daily routine.
Solar energy brings us great ease; we can enjoy hot water whenever we want, which solves the trouble of bathing.
The idea behind using solar power is quite simple: solar panels collect sunlight to heat the water, giving us ready access to it.
Solar energy offers us convenience, and at the same time, we should keep exploring its new developments and research.

The sun is a star. In the sky there are thousands of stars like the sun. They are as large as the sun and as hot as the sun. At night you can see any stars, but in day-time you can only see one star---the sun.
The sun is much nearer to us than any other star. That is why it looks like the biggest and brightest to fall the stars. The distance of the sun from the Earth is as much as 150 million kilometers. Most of the stars are thousands of light years away from the Earth.
Do you know what a light year is? Nothing in the world travels faster than light. It travels 300,000 kilometers a second. One light year is the distance that light travels in one year.

An Earthship is a type of passive solar home made of natural and recycled materials. Designed and marketed by Earthship Biotecture of Taos, New Mexico, the homes are primarily constructed to work autonomously and are generally made of earth-filled tires, utilizing the thermal mass construction to naturally regulate indoor temperature. They also usually have their own special natural ventilation system. Earthships are generally off-the-grid homes, minimizing their reliance on public utilities and fossil fuels.
Earthships are built to utilize the available local resources, especially energy from the sun. For example, windows on the sunny side admit light and heat, and the buildings are often horseshoe-shaped to maximize natural light and solar gain during winter months. Likewise, the thick, dense outer walls provide effective insulation against summer heat.
Internal, non-load-bearing walls are often made of a honeycomb of recycled cans joined by concrete and are referred to as tin can walls. These walls are usually thickly plastered with stucco.
The roof of an Earthship is heavily insulated---often with earth or a dobe---for added energy efficiency.

Solar cars combine technology typically used in the aerospace, bicycle, alternative energy and automotive industries.
The design of a solar vehicle is severely limited by the amount of energy input into the car. Most solar cars have been built for the purpose of solar car races.
Exceptions include solar-powered cars and utility vehicles.
Solar cars are often fitted with gauges as seen in conventional cars. In order to keep the car running smoothly, the driver must keep an eye on these gauges to spot possible problems.
Cars without gauges almost always feature wireless telemetry which allows the driver's team to monitor the car's energy consumption, solar energy capture and other parameters, and free the driver to concentrate on driving.
Solar cars depend on PV cells to convert sunlight into electricity. In fact, 51% of sunlight actually enters the Earth's atmosphere.
Unlike solar thermal energy which converts solar energy to heat for either household purposes, industrial purposes or to be converted to electricity, PV cells directly convert sunlight into electricity.
When sunlight (photons) strike PV cells, they excite electrons and allow them to flow, creating an electric current.
PV cells are made of semiconductor materials such as silicon and alloys of indium, gallium and nitrogen. Silicon is the most common material used and has an efficiency rate of 15-20%.
