Whats The Future Of Energy ?

Energy demands is rising each and every day. We start to use a lot of smart gadgets and need for greener sources of energy has never been such higher. Whats the source for energy to meet our demands in the future ? I have posted my views. Comment yours.

60% of todays energy we consume is from non renewable sources. Most from Coal and Oil. But experts think that it’s not going to be long before oil prices fall to the ground as people move towards alternate sources of energy.

For too long it has been thought that “Nuclear” as the alternate source of energy for these fuels. But two accidents have proven that the cons of these sources of energy is far higher than its pros.

So where do we get our energy from ?

As our text book says, the sources of energy still remains the same.






Experts feel that within this decade, there would be huge jump towards last three sources of energy.

Starting from the improvements in battery technologies, companies like Tesla is starting to prove that electricity from these sources to fulfil our energy demands is possible.

Take an example of Tesla SolarCity in which a entire city is powered entirely from Solar power all from day to night and Tesla Solar Roof to PowerWall, the solar power for every home revolution in the field of energy is just beginning.

Just like early days of internet, huge startups are starting everyday with technologies that can revolutionise the industry just like the startups revolutionised the computer world half a century ago. Investors are really starting to put their money trusting new companies and there is a huge possibility that within years, this field would never be the same again.



But how would it happen ?

  • Phase 1: The world undergoes the first large growth in the production of clean energy such as wind and solar (2000–2020).
  • Phase 2: Growth in global energy needs is now met predominantly by renewable energy sources rather than fossil fuels (2020–2050).
  • Phase 3: Clean energy becomes dominant in the energy mix globally, surpassing the amount generated from gas, coal and oil (2050–2080).
  • Phase 4: The end point of the transformation of the global energy system when virtually all energy generated comes from renewable sources complemented with nuclear (2080–2100).

The biggest game-changer in this energy revolution is the fast-declining cost of solar power.

The large reduction in cost comes from multiple factors. A solar system consists of solar panels, a mounting mechanism, an inverter for DC to AC conversion, cables — and for industrial projects, transmission lines — plus significant “soft costs” including installation, company overhead, contracting and so forth. The pure costs of a 1 kW panel alone dropped from $2,055 in 2010 to $687 in 2016. The largest factor has been a massive material cost reduction by reducing the thickness of solar wafers while the amount of light captured has increased substantially.

In addition to newer ways to generate energy in different ways, technology is also improving to help us reduce our energy consumption. In the past year alone, the new products consume 30% less power than their predecessor.

With improvements in both the sides, its interesting to see where it takes us. Comment your views.




  1. Hydrogen can be used as an alternative for petrol, diesel in automobiles. Research has been done and came out with flying colours. HONDA CLARITY IS AN EXAMPLE. Only cons is need for platinum for replenishing and few hydrogen fuel stations…

  2. Well, I think that the future energy needs can also be satisfied with another alternate clean source like hydrogen. Recently Tata and ISRO launched a zero emission bus which is powered by hydrogen , while Toyota mirai which is a hydrogen fuel cell car was launched back in 2015. Many researches are still going on for using hydrogen commercially in vehicles since it is highly explosive at higher concentrations. So I think that focussing on this area along with other alternatives can also satisfy clean energy demands.
