Solar Energy is best option of Coal power plant. It is safe as well as very minimal impact on environment.
Explanation:
Solar energy is one of the best ways to build an energy. It uses captured sunlight and create photovoltaic power or “concentrated solar power” for solar heating. The use of solar power is increasing day by day.
Now subway, buses, college, institute all use solar energy for their electricity consumption. Recently solar powered aircraft whose name is impulse2 is made. Because of zero emission of carbon dioxide government move towards this option.
Disadvantage: It is very costly and takes more space for installation

The first stage of both technological design and scientific investigation would be identifying a problem or need. Both are similar in so many ways when conducting an investigation. More or less each step corresponds to each other. For instance, the first stage both needs to identify something. For scientists, they identify problem while, while for engineers, they identify a need.
