Question

how are non conventional resources of power useful to us

Answer 1

Non conventional resources of power are useful to us in the following ways:-

as solar energy can be used in solar cells to produce electricity.It is also used in solar heaters ,solar cookers,solar dryers besides being used as community lighting and traffic signals.

Wind Energy also generates electricity yeah but windmills are costly or expensive to purchase and maintain.

Nuclear power, Geothermal,Tidal energy also produce electricity .but they have disadvantages and advantages also refer to the txt bk pg33

Thanks, I hope it helps

NON-CONVENTIONAL ENERGY SOURCES: A SOLUTION TO GLOBAL WARMING

staffEarth EnergyNon-Conventional Energy Sources, Solution to Global Warming

Global warming is defined as the gradual increase in the overall temperature of the earth’s atmosphere that attributes to the Greenhouse Effect that is caused by the increased levels of carbon dioxide and other such pollutants.

Finding clean non-conventional sources of renewable energy sources such as wind power with the use of wind turbines, solar energy, or tidal power is vital when trying to achieve sustainable development and find alternative sources that do not contribute to the carbon footprint we are leaving on the environment.

Wind, solar, and hydroelectric energy are increasing in popularity and with new advances in technology and further research, we can find better solutions that are more cost-effective and efficient without contributing to Global Warming and the pollution of our environment.

THE EFFECTS OF GLOBAL WARMING

Effects due to global warming caused by use of fossil fuels nuclear power plants and other non-renewable sources can include rising sea levels due to thermal expansion because of melting glaciers and ice sheets, warming of the ocean surface, and increased temperature stratification.

One of the best ways to reduce these effects of global warming is to reduce the use of fossil fuels.When we burn fossil fuels, we increase the levels of greenhouse gasses that are being introduced into the atmosphere.

Conclusion

Many non-conventional energy sources can be employed to help reduce the threat of global warming. Any energy source that is cost-effective and renewable and reduces our dependence on fossil fuels without emitting any pollutants or other toxins into the atmosphere is a good start.

Non-conventional energy sources include solar energy, tidal energy, geothermal energy, and wind energy just to start with. The source of non-conventional energy typically comes from a flow source, and these resources cannot be exhausted or depleted. Along with the technological development and advances in non-conventional energy sources, we see reduced costs in the future and less negative impact being placed on our environment.
