Writing II

Write a news article about Green Energy. Use the following prompts.

Green Energy – The Future of Sustainable Living

Green energy is the type of energy that is generated from a natural source such as sunlight, wind or water. It often comes from renewable energy sources although there are some differences between renewable and green| energy. Renewable energy is the generation of energy from infinite sources but can negatively impact the environment. However, green energy is renewable energy that does not produce carbon emissions or negatively impact the environment.Β 
Green energy is perpetual in nature and it never comes to an end. Green energy is the most advantageous source of energy as it doesn’t impact the environment negatively at all. However, the economic production and consumption of green energy is a challenging task. Though the developed countries in the present world have made good progress in the production and consumption of green energy, it is a very challenging task for developing countries such as Nepal regarding the production and consumption of green energy.
