Research into alternative, clean energy is a hot issue for mass media and politicians."Clean" implies that no harm is done to the environment when the energy is produced.It sounds like a worthy mission for the humanity — to invent and implement technologies which allow us to enjoy all the technological society commodities being concurrently nature conscious, i.e. to keep water, land and air clean for our descendants.An old native Americans' wisdom says "We do not inherit the earth from our ancestors, we borrow it from our children" and the borrowed should be run with care and returned in a good working state.

2. _____Most people do understand that burning huge amounts of oil and gas is the way to nowhere.We'll either end up with a devastating ecological catastrophe or our industries will collapse when we run out of oil and gas supplies, which are non-renewable and are expected to run out relatively soon.The solution was provided by science fiction writers a century ago — solar and wind energy should be used instead of fuel.However, the manual on how to produce and store it in large quantities hasn't been provided yet.
3. _______
It's true that nowadays it's still too early to say that we are ready to switch to a clean energy.Our industries have got used to energy overconsumption, and people are unlikely to consent to give up their privilege of comfort.However, it would be wrong to state that nothing is being done and that we are not moving to our goal.There is evidence that solar energy can be used in real businesses and it doesn't lessen the business' success.

4. _________
Solar Sailor has been successfully operating in Sydney, Australia, since 2000. It is a large ferry used for public transportation and tourist cruises.In spite of the fact that the ferry moves slower than other ferries, it's particularly popular with people, tourists especially.Solar Sailor is used for sightseeing, for cocktail and dining cruises, for corporate and family events like weddings and anniversary parties.It is also used for taking people from one place to another as a conventional transport means, which holds as many as 80 people on board.
5. ___________
Solar Sailor is a renewable energy hybrid able to use solar, wind, battery or liquid petroleum gas, either individually or in combination.The unique feature of the ferry is its "solar wings".Inspired by insects, which use their wings as solar collectors, the Solar Sailor's wings are able to angle towards the sun.They can be stowed away in a storm, or when not wanted.The solar wings or solar panels can charge the ferry's batteries in four hours, and they can power the ferry independently for up to six-hour cruise, day or night.
The length of the ferry is about 21.5 meters and it can move at a maximum speed of 10-12 knots, which is around 20 km per hour (1 knot equals 18.7 km per hour).
6.___________
The speed may not look very impressive, but Solar Sailor creates low noise and no air and water pollution.It may be considered a baby step in clean technology development but every solid plan has to walk through baby steps.
A. Technical characteristics of the solar energy device.
B. The engineers' comments on the solar technologies implementation.
C. A possible solution for the "alternative energy's case".
D. Good intentions and the real life situation.
E. Alternative energy technologies' prospects for the future.
F. The reasons to look for alternative sources of energy.
G. The evidence that solar energy can be used by businesses
