We had a good run with fossil fuels. They have been the source of paramount energy that has fueled up many generations. But, as they say – All good things must come to an end, Earth’s liquid oil deposits are soon drying up!
And that isn’t a surprise to anyone, anymore. Scientists are already prepping up for what’s next. Cleaner & more efficient sources of energy that hold a huge potential to replace the traditional solar & wind power.
Here’s a roundup of the best 5 alternative energy sources:
Algae as Biofuels
Who would have thought one of the tiniest aquatic organisms can be an amazing source of energy? Algae are proving to be one of the major fuel sources in the future as they convert sunlight into energy & store them as oil. Also, Algae can be genetically modified to produce biofuels directly in an efficient manner.
Alabama is home to the World’s first algae biofuel system.
Human Body Heat
Amongst all the alternative energy resources, body heat remains the most interesting one.
The human body generates energy by muscle movement & other processes. While the energy generated by the human body during movements reduces significantly when the motion stops, the energy generation by body heat continues even when sleeping as a by-product of metabolic breakdown. Thermoelectric generators are the torch bearers of this alternative energy source as they convert body heat into electric energy.
Green Hydrogen yields an effective amount of high energy while producing zero pollution. Rather than hydrogen being obtained from fossil fuels, green hydrogen is produced from renewable sources of energy such as wind, water or sun. Electrolysis is used to produce hydrogen from renewable and grid electricity.
Green hydrogen holds potential to help decarbonize industrial processes, gas heating and heavy transport.
Molten salt reactors
Due to serious radiation risks, nuclear energy is never going to be considered a clean & efficient alternative energy source. While the energy produced in the fission reaction is beyond any other source, it is frowned on for various reasons. In contrast the molten salt reactors can provide carbon-free electricity with fewer radiation risks than traditional nuclear energy.
Global research for Molten salt reactors as an alternative energy source is led by China
To be able to produce energy at an industrial scale by power of fusion has been a dream for many scientists. While I’d agree the complete victory over this lies a little ahead, this like the generation of energy via body heat remains one of the most interesting & promising ones. Fusion works by fusing deuterium & tritium – two isotopes of hydrogen. Also, this process has no threat like the nuclear fission reactions & is completely pollutant-free.
The first ITER (International Thermonuclear Experimental Reactor) was built in France
The future is exciting
With the world racing to adhere to the guidelines set out in the Paris Agreement of 2016, it is time our generation finds out an effective clean alternative energy resource. And honestly, the innovations in this sector has been amazing.
There are good times ahead if we can charge our watch by our body heat. Right?
