Hydropower is the most widely used renewable energy in the world, and currently accounts for 16% of the total electricity production. With over 60 countries using it to meet half of their electricity calls, hydropower is seen as a very attractive investment for countries around the globe and a sub-sector of GreenTech that is doing amazing things for sustainability.

Advantages of hydropower

Despite upfront infrastructural costs, hydropower is one of the cheapest renewable energies available. Maintenance is also low-cost and dams can be used for 50 to 100 years, so besides the actual infrastructure, there are no other associated costs…


GreenTech is becoming an increasingly appealing sector for investors, executives and entrepreneurs. Global efforts to combat climate change such as the Paris Agreement signed by 195 countries, each countries’ own environmental targets and a rise in public awareness is driving the GreenTech sector to develop at high speed.

In the renewable energy sector only, there are around 6,500 companies operating just in the UK.

As cryptocurrencies continue to increase drastically in value and popularity, questions are being…


Renewable energy is powering 29% of the world’s total energy consumption, with solar energy being the third largest renewable source. Beaten only by hydropower and wind, solar energy has become increasingly popular over the last decade. It is also one of the most heavily funded renewable sources, with a global investment of $141 billion. Germany, the United States and China are some of the biggest investors.

The benefits of solar energy

We can never run out of solar energy: it is available everywhere and every day, making it one of the best natural energy sources. It is also a clean…


Global warming is an undeniable threat, and human activity is the main cause of it, as reported by the Intergovernmental Panel on Climate Change. Whilst world leaders get some of the blame for climate change inaction, it is also up to individuals and businesses to do their part.
