Climate Crisis and Clean Energy
What is climate crisis?
The term climate crisis describes climatic changes and global warming with their sequences. That means changing the pattern of weather, related changes in oceans, land surfaces and glaciers etc.
Climate crisis can be seen all over the world and comparatively it is higher in developed countries. Especially in last two decades, can see a higher rate in crisis of the climate. A major threat for the climate crisis is the irregular generating and application of energy.
Present energy sources
In present world, the main sources of energy that utilized by the human are,
Coal
Natural gas
Nuclear energy
Fossil fuel
Hydro power
Biomass energy
The above sources clearly identify that the present world is using both natural sources and artificial sources to fulfil the need of energy. Nuclear energy is used as the main artificial energy source.
If we consider the flow of above power sources, it shows that most of the natural sources are depreciating but regenerating the power sources are not balanced with the depreciation. So it is much important to keep the balance to get the use of sources continuously.
It takes thousands and millions of years to regenerate fossil fuels and other sources. So it is impossible to keep the balance because the power is needed everywhere and always. So renewable and safety power sources are a must to the future world.
Climate crisis with regard to energy sources
Considering nowadays, many climatic changes have been taken the place.
In the reaction of combusting coal and fossil fuels, adverse gases are emitted.
Ex: Nitrogen Oxides – N2O, NO2
Carbon Oxides – CO, CO2
Sulphur Dioxide – SO2
NH3
CO2 and N2O are the main greenhouse gases. They are mainly caused in global warming.
What is clean energy?
Basically, clean energy means the energy that comes from renewable and zero emission sources that do not pollute the environment.
Clean energy is the most effective tool to fight against climatic crisis.
So clean energy describes the energy production methods with the least amount of impact on the environment.
There are many sources for clean energy, that human can use unlimited.
Solar Energy
The main source for solar energy is the sunlight. When sunlight falls into the solar panels, they absorb sunlight and give energy. There are no any chemical reactions take place and also does not emit any gas. So it does not cause for any climate crisis.
Wind Energy
It is a plentiful source of clean energy. Turbines can be used to drive generators which feed electricity into the national grid. Nowadays, electricity-generating wind turbines are proliferating around the globe.
Hydro Energy
Hydro power is the most commercially developed, renewable energy source. A dam/ barrier or a large reservoir can be used to create a flow of water which can drive a turbine, to generate electricity.
Tidal Energy
It is another form of hydro energy. The tidal is used to drive turbines.
Geothermal Energy
The natural heat below the earth’s surface can be used to heat homes directly or to generate electricity.
Nuclear Energy
In here, nuclear reactions take place to produce heat. So the steam turbines can produce energy as electricity.
Biomass Energy
Biomass, which is turned into biofuels, is also sometimes considered clean energy, although some debate exists as to whether biofuels are actually environmentally friendly.
Importance of clean energy
In case of climatic changes,
The glaciers melt
Irregular rains take place
Forest fires spread
Acid rains
The rain acidify with the emission of carbon oxides, nitrogen oxides and Sulphur dioxide. Because of that, the forests and cultivated lands may destroyed
Animals suffer from various kind of diseases and sometimes the end is death
Skin diseases and difficulty in breathing are common in humans.
Without expostulations, environment warns human for optional energy sources which are clean.
Clean energy helps in conserving the natural resources. It give hands to a green world. It protects the environment and secure the safety. Water ways and air ways will not be polluted. Human and animal will be healthy. Global warming will be controlled easily.
So it is clear that clean energy is a must thing to prevent climatic crisis. So as human, we have a response to use clean energy for a sustainable and secured world!!!
