Which pair of resources is renewable?
Renewable resources include solar energy, wind, falling water, the heat of the earth (geothermal), plant materials (biomass), waves, ocean currents, temperature differences in the oceans and the energy of the tides.
What are the importance of renewable resources?
THE IMPORTANCE OF RENEWABLE ENERGY They differ from fossil fuels principally in their diversity, abundance and potential for use anywhere on the planet, but above all in that they produce neither greenhouse gases – which cause climate change – nor polluting emissions.
What are the applications of renewable energy?
2. Renewable energy resources
| Energy source | Energy conversion and usage options |
|---|---|
| Solar | Solar home system, solar dryers, solar cookers |
| Direct solar | Photovoltaics, thermal power generation, water heaters |
| Wind | Power generation, wind generators, windmills, water pumps |
| Wave | Numerous designs |
What is renewable energy advantages and disadvantages?
Disadvantages of renewable energy resources
| Energy Resource | Advantages | Disadvantages |
|---|---|---|
| Hydroelectric power stations | Clean and cheap to run | Expensive to set up and output could be affected by drought |
| Solar cells | Clean and cheap to run | Not always sunny and output does not always outweigh initial cost to set up |
What are 2 advantages of solar energy?
Advantages:
- Solar power is pollution free and causes no greenhouse gases to be emitted after installation.
- Reduced dependence on foreign oil and fossil fuels.
- Renewable clean power that is available every day of the year, even cloudy days produce some power.
- Return on investment unlike paying for utility bills.
What are the two main limitations of solar energy?
The Disadvantages of Solar Energy
- Location & Sunlight Availability. Your latitude is one of the main factors in determining the efficacy of solar power.
- Installation Area.
- Reliability.
- Inefficiency.
- Pollution & Environmental Impact.
- Expensive Energy Storage.
- High Initial Cost.
What’s bad about solar energy?
Solar panels are composed of photovoltaic (PV) cells that convert sunlight to electricity. When these panels enter landfills, valuable resources go to waste. And because solar panels contain toxic materials like lead that can leach out as they break down, landfilling also creates new environmental hazards.
What is disadvantage of renewable energy?
One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. This may mean that we need to reduce the amount of energy we use or simply build more energy facilities.
What are the limitations of renewable energy?
Disadvantages of Renewable Energy
- The Electricity Generation Capacity is Still Not Large Enough.
- Renewable Energy Can be Unreliable.
- Low-efficiency Levels.
- Requires a Huge Upfront Capital Outlay.
- Takes a Lot of Space to Install.
- Expensive Storage Costs.
- Not Always a Commercially-viable Option.
- It Still Generates Pollution.
