Cleaner and more reliable sources of energy must be found or global warming will accelerate, and it will be impossible to meet energy demands. |
|
As the process of global warming speeds up and demands for energy rise, we need to find cleaner and more sustainable sources of energy, |
|
If global warming continues and the demands for energy increase, we shall be forced to seek cleaner and more sustainable sources of energy. |
|
The demand for cleaner and more reliable sources of energy will increase if global warming continues and energy requirement increase. |
|
As global warming accelerates and our energy demands continue to rise, we have to have cleaner and more sustainable source of energy. |
