Disadvantages of renewable energy

Answer 1

The Disadvantages of Conventional Energy sources are:

1) Very costly production cost.

2) Heavy transmission & distribution loss.

3) Limited reach.

4) Big threat for environment & public health.

5) Cause of global warming, greenhouse effect, acid rain etc.

6) Uncertainty in availability.

7) Electricity tariff is increasing at about 8 to 10% p.a. on an average.

Answer 2

1. It creates pollution

2. Disposal of by products is difficult

3. These are depleting at fast rate

4. Not available in abundance

5. Burning of non renewable resources creates health problems

Answer 3

Renewable energy is energy derived from sources that will not run out. Some of the present disadvantagesare:

• solar -- panels are expensive. Most Governments are not all willing to buy home generated electricity. Not all climates are suitable for solar panels.
• wind -- turbines are expensive. Wind doesn't blow all the time, so they have to be part of a larger plan.
• waves -- different technologies are being tried around the world. Scientists are still waiting for the ultimate development.
• tides -- barrages (dams) across river mouths are expensive to build and disrupt shipping. Not many places around the world are suitable. Smaller turbines are cheaper and easier to install.
• rivers -- Dams are expensive to build and disrupt the environment. Smaller turbines are cheaper and easier to install.
• geothermal -- Difficult to drill two or three kilometers down into the earth.
• biofuel -- often uses crop land or crops (like corn) to produce biofuel so the price of cheap food goes up.

However, the disadvantages are greatly outweighed by the advantages - a reduction in global warming and climate change.

Answer 4

However, renewable resources rely on the environment. If there is no sunlight or wind, energy cannot be produced. Lots of money have been put into research, technology and building of the gadgets, making it extremely expensive and unaffordable for a few poor countries.

Answer 5

Advantages are:

• Cheap to produce large quantities of power
• Building power plants are easy and can be done near cities
• Readily available/convenient -price is lower

  Disadvantages Are:

• Burning fossil fuels produce CO2 --> Global warming
• Nuclear=Danger
• Fossil fuel supply will decrease --> Price increase
• Nuclear waste will remain toxic for many thousands of years

Answer 6

• Solar: Sun doesn't always shine, so a storage system or an alternative support system is needed
• Wind: Wind doesn't always blow, so a storage system or an alternative support system is needed
• Some of the present systems are experimental, as we search for the best solutions.

Answer 7

it is costly

Answer 8

they r not unrenewabl lol

Answer 9

there is no comments from my side
