Green energy is energy generated from natural resources such as sunlight, water, tides, wind, rain, geothermal heat and other forms of energy resources that never get depleted. Hence, it’s renewable energy.
More importantly, unlike traditional sources of fuels, renewable sources of energy may provide an uninterrupted source of power without warming or polluting the planet.
Renewable energy is getting more high-tech that by 2022, it is estimated that the green energy industry will be worth half a trillion dollars worldwide.
But what is green energy today? Brush up on the basics quick.
In five powerful truths, learn why green energy means good, gold, and the future.
There are More than 7 Types of Renewable Energy
There’s no one-size-fits-all solution for greening a nation.
These are the common types of renewable energy:
- Hydropower converts energy from the force of flowing water to electricity. This is the leading source of renewable energy in the world harnessed by countries like China, Canada, Russia and the U.S.
- Solar energy converts sunlight into usable energy using Photovoltaic cells in solar panels
- Wind energy relies on wind turbines to harness the wind as a power source
- Biomass extracts energy from organic sources such as wood, biofuels, solid waste and more
- Geothermal energy derives energy from earth’s internal heat

But nature has no limits, which is why scientists have also started to experiment collecting green energy from novel sources such as:
- Body heat. Aside from wearable tech devices, a train station in Sweden runs on the warmth generated by commuters.
- Dance power. Dancers who can stomp and bounce on the Sustainable Dance Floor can generate anywhere between two and 20 joules of kinetic energy from pressure and heat.
- Coffee waste energy. The liquid waste after processing coffee beans can actually be used as biofuel and relies on a special fuel cell to convert waste matter into power.
Other clean solutions on the way include turning carbon dioxide into stone and biofuel from algae could potentially replace diesel and gasoline.
Four Countries in the world generate 100% of electricity from Green Energy
Four nations in the world are able to generate 100% of their electricity through renewable energy: Albania, Lesotho, Nepal and Paraguay.
Other countries have also pledged to eliminate the use of fossil fuels to generate electricity and many are fast catching up. The most notable of which are:
- Costa Rica has achieved 95% renewable electricity
- Scotland is building the world’s largest floating wind farm
- Germany, a relatively cloudy country, was able to power every home with renewable energy for the entire 2018
Going green is no longer a matter of technology, but a matter of will and execution.

Over 58% of people surveyed don’t understand Green Energy
Research commissioned by Good energy UK with YouGov found that 8 out of 10 people surveyed found the topic of renewable energy very important.
However, while 84% of the people surveyed are passionate with renewables, over 58% of people polled would join the bandwagon if only they understand the impact of renewables.
When asked about renewable energy, the majority responded: “What is Green Energy?”
Those who understand Green Energy are willing to pay for it
Market research firm Maslansky & Partners sat down with “media informed customers” and Vox voiced out the public sentiment over green energy: “We want clean, modern energy, and we’ll pay for it.”
In fact, private companies such as Google, Ikea, Apple, Facebook, Microsoft, Coca-Cola, Nike and even Lego are already investing in 100% renewables, among more than 150 corporates worldwide.
Global automotive companies are also on the race for innovating Hydrogen fuel cell cars or any reliable mode of transport that runs on green energy.

The world is under threat as it nears one-fifth of its Carbon limit
The terms “climate change” and “global warming” may not sound alarming for some people but the world has only one-fifth of the allowable “carbon budget” before it heats up to more than 1.5 degrees Celsius.
Fatal symptoms have already shown up:
- Fishes have started to disappear and are shrinking in population by 35%
- Antarctic wildlife has collapsed by 90% as rising temperatures have forced species to migrate
- Extreme heat is drying up lakes, setting up forest fires and weather patterns we have come to expect are changing
Kill the Biggest Threat
Relying on fossil fuels—such as hydrocarbons, primarily coal, fuel oil or natural gas, formed from burning dead plants and animals—creates greenhouse gases, smog and toxic pollutants that can gradually kill us all.
Whereas, green energy can power the world less the pollution or the planet-warming effects.
Thus, if green energy is a necessity, it’s because life is.
