Study the information in the table
Renewable energy source | Its advantages | Its disadvantages |
Wind |
Very clean - free |
Noisy - |
Solar | Clean - quiet | Its panels contain toxic substances and expensive |
Biomass | Reduces rubbish-animal residues- available | Air polluting - expensive |
Let’s make short expository paragraphs in which we compare renewable energy and draw conclusions. The aim is not to present arguments but to explain facts by contrasting and comparing:
Note that the adjectives in red must be in the superlative form.
Here is the structure of your paragraphs:
On the one hand, ……………… .On the other hand, …………………………..However, ……………………………………………the ………………………..
Simple paragraph:
SOLAR ENERGY
On the one hand, Solar energy is clean. On the other hand, its panels contain toxic substances. However, of the three renewable energy sources, solar energy is the quietest.
Now do the same with ‘biomass’ and ‘wind’.
BIOMASS
On the one hand, …………………………. .On the other hand, ……………………..However, …………………………………the ………………………..
WIND
On the one hand, ……………. .On the other hand, ………………………………..However, …………………………the … …… … ……
BIOMASS
On the one hand, biomass reduces rubbish and animal residues. On the other hand, it is air polluting. However, of the three sources of energy, it is the most available.
WIND
On the one hand, wind is free. On the other hand, it is noisy. However, of the three sources of energy, it is the cleanest.
