Due to growing world population and increasing wealth, demand for energy – specifically electricity – is rising, especially for the 1.3 billion people who don’t have access.
The most commonly used source for electricity production today is coal; 41% of all electricity is produced from coal, according to the World Coal Association. Due to its high level of pollution (water and air pollution during mining and air pollution during burning) and often miserable circumstances for miners, we can conclude that this is not a sustainable source for electricity. Moreover, some serious environmental problems related to global warming and climate change have made people aware of the brutal consequences that they may have to face if a switch to green and clean energy is not made sooner. This led to use of alternative or renewable energy sources.
When looking at sustainable electricity resources, we commonly identify four: solar, wind, hydro and biomass. Each of them is renewable, but that doesn’t necessarily make them sustainable if it is not environmental friendly, social sustainable and economically sustainable.
What is Sustainable Energy?
An energy source can be considered as sustainable if it fulfills 3 demands of energy.
·The energy can be naturally replenished.
·Technology should improve energy efficiency.
·The long term availability
Sustainable Energy is one which is able to meet the growing demand of today’s people without compromising the demand of the people that would require it in future. All renewable energy sources like solar, wind, geothermal, hydropower, wave and tidal power are forms of sustainable energy. These energy sources have been here since centuries and are here to stay till life is available on earth. Renewable energy sources have low environmental impact, widely available and are naturally replenished.
The energy of the world needs to grow with the maturity of our technology. Changes in technology have given rise to many other alternative sources of energy which can be harnessed through various modern techniques. There is still plenty of work to be done. This is in relation to the population that is vastly using modern devices that add to the ever increasing energy need. For us to cope with this energy need, Profit&Comfort Energy Ltd. exercise a lot of keenness when it comes to our efforts in making energy accessible and available to many people at all times.
Societies around the world are on the verge of a profound and urgently necessary transformation in the way they produce and use energy. This shift is moving the world away from the consumption of fossil fuels toward cleaner, renewable forms of energy. The rapid deployment of renewable energy has been driven mainly by a wide range of objectives (drivers), which include advancing economic development, improving energy security, enhancing energy access and mitigating climate change.
Renewable energy includes all those sources that do not cause any harm to environment and have minimal impact on the surrounding environment. Sustainable is much more a wider term and includes all type of energy sources. Sources such as solar, wind, geothermal, hydropower, wave, tidal and hydrogen are renewable as well as sustainable since they have minimum impact on the environment whereas Nuclear energy or nuclear power is not considered as renewable but it is sustainable as it pollutes the environment. This is the only reason that it is said that all renewable energy sources are sustainable but all sustainable energy sources are not renewable.
