The science concerning renewable energy is getting better every day

Right now, renewable energy makes up a very small part of the entire energy sector of Bangladesh. But as we move into the future, and concerns about the environment become too great to ignore, exploring cleaner and greener sources of energy becomes the need of the hour.

Our economy is booming, and our population is growing, so it goes without saying that our energy requirements are immense. There is plenty of scientific evidence that burning fossil fuels indiscriminately is not sustainable in the long term, so we do need to up our game in looking at alternatives.

The good news is that the science concerning renewable energy is getting better every day, while technology is giving us sustainable solutions. Solar, of course, is the obvious choice when it comes to sustainability, but it is not the only one.

A recent breakthrough from Hong Kong scientists, for example, gives us great hope for what is possible. Using energy-harvesting technologies, these scientists were able to power 100 small LED light bulbs using a single droplet of rainwater.

This technology harnesses the kinetic energy of raindrops, and it does so directly without requiring a large amount of raindrops for it to work.

This is great news for a country like Bangladesh, which is prone to getting heavy amounts of rainfall for much of the year. Rain need not be a cause of woe for our citizens: It can, in fact, generate a tremendous amount of energy, which will in turn flow back into our industries and households, lifting up our economy, and our lives.

In the year 2020, we must look to new ways, and embrace the future. The technologies that appear novel at first may be the ones that end up saving us later.
