The correct answer is Unreliable supply.
What are the disadvantages of renewables?
Disadvantages of renewable energy resources
At the present time, most renewable energy generators are expensive to set up. Also, sources such as wind turbines and solar cells rely heavily on the weather. If it is not a windy day, wind turbines will not turn.
What are the disadvantages of energy sources?
Cons:
- There is impact on environment.
- Can potentially pollute the air, soil, and water bodies.
- The burning of coal emits CO2, SO2, toxic heavy metals, cadmium, arsenic, and mercury.
- Clean Coal involves costs.
- Coal source is finite.
- Byproducts of coal mining include arsenic, SO2, selenium, and mercury.
What are the advantages and disadvantages of renewable energy source?
- Renewable energy won’t run out.
- Maintenance requirements are lower for renewable energy.
- Renewables save money.
- Renewable energy has numerous environmental benefits.
- Renewables lower reliance on foreign energy sources.
- Higher upfront cost.
- Intermittency.
- Storage capabilities.
What is the advantages and disadvantages of renewable energy?
Renewable energy sources are clean to use as there are fewer greenhouse gas emissions. The technology required is often expensive to purchase. Usually, the energy is produced at a slower rate than when using fossil fuels. Due to use of a stable source of energy, the cost of renewable fuels does not change much.
What is a disadvantage of biomass as an energy resource?
One of the disadvantages of biomass energy is the amount of space that it requires.Another disadvantage is that biomass energy is not entirely clean. Some greenhouse gases are still produced; although the levels of these gases are far less than those produced by fossil fuels.
What is the disadvantage of using nonrenewable energy resources?
1. One of the major disadvantages of non-renewable energy is that it is time-consuming.Non- renewable energy can be dangerous and cause respiratory problems to humans because sources like fossil fuels emit gases such as carbon monoxide.
What are some disadvantages of non-renewable resources?
Disadvantages of non-renewable energy
- It produces greenhouse gases.
- Its by products cause damage to the environment.
- Once exhausted they are not easily replenished.
- Rising cost.
- Its residual products are generally non-biodegradable.
- Its products pose potential threat to human health.
- Responsible for acid rain.
What is electricity advantages and disadvantages?
Advantages and Disadvantages of Electricity Generation
| Energy resource | Generation of electricity |
|---|---|
| Oil and natural gas | The burning of oil or natural gas produces high pressure steam that is used to drive turbines |
| Coal | Coal is burned and the heat energy is used to produce high pressure steam |
What are the 2 main disadvantages of solar energy?
However, solar energy does still have significant disadvantages which we should be aware of. The 2 main disadvantages of solar energy are dependence on weather conditions and the inability to store electricity. Solar energy output depends mostly on direct sunlight.
What makes renewable energy sources unreliable?
But many of the renewable sources are unreliable, including wind and solar energy, and cannot respond to increased demand – sunny and windy weather cannot be guaranteed. Renewable resources have no fuel costs, but the equipment used is expensive to build.
What are 3 disadvantages of biomass?
While the advantages of biomass energy are plenty, there are also some shortcomings, including:
- Biomass energy is not as efficient as fossil fuels. Some biofuels, like Ethanol, is relatively inefficient as compared to gasoline.
- It is not entirely clean.
- Can lead to deforestation.
- Biomass plants require a lot of space.
What are the disadvantages to using forests as a source of energy?
Over-exploitation of forests has serious environmental effects such as deforestation, destruction of ecosystems and animal habitats, accelerated soil erosion among others. Air pollution occurs from burning of the energy sources. Use can destroy forests or homes through accidental fires.
What are some disadvantages for geothermal energy?
What are the Disadvantages of Geothermal Energy?
- Location Restricted. The largest single disadvantage of geothermal energy is that it is location specific.
- Environmental Side Effects.
- Earthquakes.
- High Costs.
- Sustainability.
What are the advantages and disadvantages of using non-renewable or conventional sources of energy?
Conventional energy sources are also known as a non-renewable energy source and have the following advantages:
- The efficiency of the energy source is high.
- This energy source is a well-known source.
- The production expenses are low.
- It is not environmentally friendly.
- When used on a longer run, can deplete soon.
What are disadvantages of using both types of non-renewable energy?
Disadvantages of non-renewable energy resources
Oil and gas will be the first to run out and then coal. When fossil fuels burn, they release carbon dioxide into the atmosphere. Research shows that a major contributor to the green-house effect and global warming is our overuse and burning of fossil fuels.
What are the disadvantages of electric current?
1) When an electric current flows through the conductor, a part of it is converted into heat energy. This is a waste of energy. 4) An additional cooling system needs to be added to the circuit to counter the heating effect. This adds to the cost.
What are the serious disadvantages of electrical power systems?
Harmonics : This is the only serious disadvantages of power electronic systems that it injects considerable harmonics both the sides, to the connected load side and to the power source side.Harmonics in supply lines also leads to radio interference with communication lines, audio and video equipments.
What are the disadvantages of solar products?
Disadvantages of Solar Energy
- It’s Not 100% Reliable. This means that when the sun is not shining, there is no generation of energy.
- High Initial Capital Costs.
- Problem of Efficiency.
- Complications When Moving.
- Materials Used to Make Solar Panels Can Cause Pollution.
- Negative Energy Balance.
- Installation Area.
What is a disadvantage or problem in using solar energy?
High initial costs for material and installation and long ROI (however, with the reduction in the cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank.
What are some advantages and disadvantages of biomass energy?
