Answer the questions below

The first steam-powered machine was built in 1698 by the English military engineer Thomas Savery. He called it “water by fire”.His invention, designed to pump water out of coal mines, was known as the Miner‟s Friend. But because the engine‟s pressure was too strong, it often caused explosions. Then in 1712, an English engineer, Thomas Newcomen (N-E-W-C-O-M-E-N) invented a more effective and pracal steam engine.The Newcomen engine remained in use for more than 50 years but they turned out to be inefficient as a lot of energy was required for the engine to run effectively. Indeed, the most important improvement in steam engine design was brought about in 1781 by the Scottish engineer James Watt (J-A-M-E-S W-A-T-T). He revolutionized the steam engine by making use of a separate condenser in the original design. When the financial backing became available, the engine was finally introduced in railways and ships. There were over 60,000 cars powered by steam during the years from 1897 to 1927 in the United States.

Nowadays, the demand for electricity for every human being is very important. Electricity at the beginning of a new era was high-tech products: light bulbs, telephones, computers, etc. However, people have been using electricity wastefully, indiscriminately, polluting the environment.To prevent wasteful using electricity, people have developed a new type of electricity, which is solar power.In fact, there are a lot of ways to use solar energy in our daily lives, as there are also a lot of solar-powered consumer products available for easy use of solar energy and a greener life. These include portable solar panels, solar chargers and solar lights. In addition, new solar innovations are being introduced to the market every day and widely applied. Therefore, among the various advantages of solar energy, the main advantage is that it can be accessed and installed by almost everyone.The use of solar power may not completely replace the grid power, but it will reduce the monthly electricity bill of the family.However, in order to use solar technology, it is necessary to ensure: the direction of receiving the sun, the direction of wind, the width of space. Weather conditions are also important for solar installations, in some places the sun does not rise in the winter, thus affecting demand for electricity.

If you want to use solar energy, you will need to expert for their advice!

1 We are looking for cheap and clean and effective sources of energy

2 Will fossil fuels be replaced by solar and wind within 20 years

3 Despite being the most polluting of fossil fuels, Coal is still the largest sources of energy worldwide
