How can replacing a coal fired power plant with several fields of solar rays affect energy sustainability?

Replacing a coal-fired power plant with solar arrays can greatly improve energy sustainability by reducing carbon emissions and reliance on non-renewable resources. Solar power is a clean and renewable energy source that can help achieve long-term environmental and economic sustainability goals. Additionally, diversifying the energy mix with solar power can enhance energy security and resilience.


How long does it take to build a coal burning power plant?

Building a coal-burning power plant typically takes about 2 to 5 years, depending on various factors such as regulatory approvals, financing, and construction challenges. The timeline can vary significantly based on the project's size and location, as well as the efficiency of the permitting process. Additionally, changes in environmental regulations or public opposition can further impact the duration of construction.

How long does it take to build a coal fired power plant?

Building a coal-fired power plant typically takes between 2 to 5 years, depending on various factors such as project size, location, regulatory approvals, and financing. The construction process involves planning, permitting, and actual building, with delays often caused by environmental assessments or community opposition. Additionally, the time frame can vary significantly based on the technology used and the efficiency of the construction management.


Why is there no coal on the moon?

There is no coal in the moon because there is no life on the moon. Accordingly, there is no plants or forests on the moon that can the basis for coal formation. Coal is called a fossil fuel because it was formed from the remains of vegetation that grew on earth as long as 400 million years ago. The plants which formed coal captured energy from the sun through photosynthesis to create the compounds that make up plant tissues. The most important element in the plant material is carbon, which gives coal most of its energy.


What advantages of gas turbine compared to steam power plant?

Gas turbines are typically much smaller and therefore cheaper. Also, steam turbines require a long time for the fuel (coal, oil, uranium) to heat up the water and so changes in power output are slow. Gas turbines rely partly on the burning and instant expansion of gases, meaning that turbines start and stop much faster.
