Answer 1

What is the difference between renewable and nonrenewable energy?

• Renewable energy can be used again and again, while non renewable energy cannot be used again and again.
• Renewable energy cost is low, non renewable cost is high.
• Maintenance cost is high in renewable energy, while it is low in non renewable.
• Resources life is infinite while it is finite for non renewable.
• Renewable energy resources are pollution free while it is not pollution free for non renewable energy resources.
• Renewable energy resources are environment friendly while it is not environment friendly for non renewable resources.

About what percent of the world’s energy comes from fossil fuels?

• Energy is obtained from fossil fuels such as coal, natural gas, oil etc. World gets about 80% of energy from these kind of fossil fuels.

About what percent of the Canada’ energy comes from fossil fuels?

• Likewise the world, Canada too uses energy from fossil fuels which comes to around 74%.

What is the maximum sustainable yield of a renewable resource?

• Renewable resources can be used again and again, and they are available in abundance. Thus, their sustainable yield is indefinite because it is supported by the regenerative capacity of the natural system.

How might the economic optimum yield level for a fishery be obtained?

• The economic optimum yield level for a fishery is obtained as per the catch from the water. The more it is caught the more will be the yield. It is measures in terms of tonnes.It also depends largely on the environmental conditions, if that is constant then the yield will be the largest of its kind over a indefinite period.
