a it absorbs carbon dioxide not only from the water but also from the air while growing b the scientists are putting a lot of effort into searching for promising alternative energy sources c engineers have been working hard to convert kinetic energy d this gas covers 74% of the universe
e these sources are stili far from meeting the world’s growing energy demands
The Future of Alternative Energy
As renewable energy technologies develop, solar, wind and water power have been put into use in recent years. They have contributed to decreasing the damage caused by fossil fuels, but (1) . As a result of this fact,
scientists have been seeking non-polluting and more affordable alternative energy sources.
To begin with, hydrogen energy is one of the most promising future energy ideas. It
will provide a big mass power as (2)_____It has already been proved that it is a clean
energy source which causes almost no pollution. The only problem is that it is found only in combination with other elements, and it requires an enormous budget to produce pure hydrogen power with today’s technology. At present, it is majorly being used in industry, aviation and heavy shipping because it’s highly expensive. Once the budget problem is resolved, it will sufficiently provide green electricity and low-carbon fuel.
In addition to hydrogen power, algae production for biofuel has a tremendous potential for clean energy. Algae is a quick-growing plant that contains energy-rich oils. It’s eco-friendly in that (3) . They can easily grow in wastewater or man-made ponds; however, algal
biofuel production requires an expensive and time-consuming process. Therefore, the number of refineries producing algal oils to supply biofuels for planes, trains and cars is far from ideal. Fortunately, attentive studies have been underway to lower the cost.
How about saving the planet by doing some exercise? Producing energy from the human body is not a new idea. There have been potential developments in human-powered electricity generators, but their efficiency is still in question. You may be surprised to hear that human power has already been used at a gym in Hong Kong and a dance club in London. In recent years, (4) , which is a free constant power source, into electrical
energy. Doing the required physical movements may be difficult for old or disabled people, though. Not to mention that it is bad news for couch potatoes! But who knows, maybe science fiction movies will actually come true.
The inevitable technological progress is, unfortunately, harming nature day by day, so clean energy sources must be used without delay. Thankfully, (5) , as we still have a long road ahead of us.
Read the text again and complete the table.
Imagine you are working on a project to find an alternative energy source for the future world. Write an opinion essay including the points below and then talk about your ideas.
