The Pros and Cons of Various Energy Types

Energy can neither be destroyed nor be created, but it can be transformed from one form to another and every energy type comes with a pro and a con. Here is the list of that.

  1. Solar Energy:
    • Pros: Low maintenance is required; do not cause noise, air and water pollution; availability is there; it’s a renewable source of energy; sustainability.
    • Cons: High implementation cost; solar panels emit harmful gases; expensive to make; needs large area.
  2. Geothermal Energy:
    • Pros: Generates fewer amounts of toxic gases; doesn’t need fossil fuels; renewable resource of energy; use the concept of heating and cooling; reliable.
    • Cons: Heavy costs are involved; it may cause earthquakes; reservoirs may get exploited.
  3. Hydropower Energy:
    • Pros: Doesn’t require much effort; doesn’t cause pollution; it’s a reliable source of energy; flexibility is there.
    • Cons: It is expensive; creates imbalance in marine life; change the temperature; people and animals are forced to dislocate; whole setup may get affected by drought.
  4. Nuclear Energy:
    • Pros: Low cost for operations; efficient as compared to fossil fuels; no or very less carbon emissions.
    • Cons: Too much radioactive waste is generated; capital cost is high; uranium is finite in amount; wastes cause pollution; nuclear waste can cause health problems.
  5. Wind Energy:
    • Pros: Clean source of energy; space efficient; low operating costs; potential is high for power generation; fuel is available worldwide; renewable and sustainable source of energy.
    • Cons: Investment is high; more noise pollution; biological impacts are there; it kills birds; maintenance cost is high; can’t be operated if there is no flow of wind.
  6. Tidal Energy:
    • Pros: Renewable energy source; effective and long lifespan; protects coastal region during high tides; no emission of greenhouse gases.
    • Cons: It is expensive and it is costly; it can’t compete energy emitted from fossil fuels; can’t operate if there is no high tide; it causes disturbance to marine life.
  7. Biofuel Energy:
    • Pros: Made from wastes; causes less pollution as compared to other fossil fuels; it is cheap and effective; renewable source of energy; not much money and investment is required.
    • Cons: Produces greenhouse gases; less efficient than fossil fuels; production cost is more as compared to fossil fuels.
  8. Coal Energy:
    • Pros: It is present in huge amounts; cost is very less; extraction process doesn’t require any tough or technical skills.
    • Cons: Impact on environment is high; causes huge pollution; though it is present in huge amounts but still it is finite; byproducts like mercury, selenium and sulphur are harmful.
  9. Petroleum Energy:
    • Pros: Present almost everywhere; reliable source of energy; doesn’t require much investment.
    • Cons: It causes pollution; improper disposal of oils can cause damage; drilling affects the local wildlife habitat; produces greenhouse gases; causes erosion.
  10. Hydrogen Energy:
    • Pros: It uses latest technology; comparatively cheaper; requires less carbon hence, less pollution.
    • Cons: Pollutes the environment; fuel efficiency is low; produces greenhouse gases; indirectly requires fossil fuels.

Some of them are conventional methods while others are non-conventional methods, encourage the use of latest methods that causes less harm to the environment.
