Is sustainable energy possible?
An issue that gives rise to constant debates is the possibility that sustainable energy, which someday could replace the entire fossil fuel-based energy system. The message is clear enough that the only way the world can combat climate change is by transforming our current energy sector. Within just a few years, we may be able to move from a fossil-fuel powered system into renewable energies. Very recently, big investors have opted to use clean energy because it has become cheaper to obtain those greater benefits. In this case its’ results in the stabilization of Co2 emissions over the long run have a direct beneficial effect on the environment and climate changes. Let's take a look into one of most popular models of the proposed transition which holds feasibility for this project. The main issue to cut down on fossil fuel usage and increase the consumption of renewable energy requires a simple question to be asked: “How Do We Reduce Fossil Fuels?” Should we choose to come up with a phase-out process until the year 2050, this goal would require the replacement of fossil fuels one by one. First on the list would be fossil fuels including brown coal (discontinued by 2035), followed by coal (by 2045) and later, the end of oil based fuels in 2050.
The fossil fuels reduction process is not an easy solution for big industry leaders of the world. But for the sake of a viable solution, let's analyze how the process would take place in some major sectors. Where sustainable energy sectors have contributed 60% of power generation worldwide in 2014, this expansion has lead to huge decline in production start-up costs. With solar panel energy collection and windmill power are now more competitive than standard coal-based power stations operating in many regions. Within the next 15 years, the share of renewable electricity could triple from the current 21% to 64%, so almost two-thirds of the world's electricity could be supported by sustainable energy sectors. This more than likely expands into other major sectors thereof, prompting them to adopt renewable energies by example. Transportation tools such as airplanes and boats can be modified further using bio-fuels and hydrogen gas to power them. The investment it normally takes to make this kind of progressive change would be much less than the estimated expenditure on fossil fuels made in the future. Since renewable energies do not require fuel, the savings over the same period would be of about 950 billion Euros a year! Only one thing is clear; if pursued with a realistic interest, sustainable energy might very well be a future that paves the way for future generations to live without fossil fuel dependance.
