Let’s all admit it, we sometimes purchase items online or from local stores without truly knowing whether they are energy-efficient or not. We just go with what the salesperson says or what is labeled on the packaging.
Of course, this does not mean that some salespersons lie in order to sell because some genuinely give good recommendations and advice on what gadgets to avoid.
However, the true information lies with the customers and you can only know the performance of a product or a gadget by reading customer reviews.
This article will attempt to give a physics guide of what energy efficiency mean and how to choose energy-efficient products.

Anaerobic digestion is also a good example of renewable energy where heat and electricity are produced through the breakdown of anaerobic material like food waste or animal manure to produce energy.
This form of renewable energy is encouraged for farmhouses.
Other forms of renewable energy like wind turbines and nuclear energy are way too expensive and impossible to be used installed for individual consumption.
