Renewable energy solutions

The global transition to renewable energy is the best way for global economies to achieve net-zero emissions by 2050 and keep global temperature increase under 1.5°C. That's because renewable energy emits significantly fewer greenhouse gases such as carbon dioxide. According to a report from the International Renewable Energy Agency (IRENA), over 90 % of the solutions in the global decarbonisation effort will involve renewable energy by 2050.

Renewable energy is exactly that – renewable. This means it’ll never run out; the sun will always shine, and the wind will always blow. And while some renewables – like wind and solar – have variable outputs, battery storage technologies make it possible to balance the electricity supply and create a more flexible and reliable grid system.

Businesses all over the world have now realised that sustainable development is key to success, which has created a growing number of well-paid, skilled jobs in the renewable energy sector – from manufacturing and construction to operations and beyond. An IRENA report predicts that the renewable energy sector could create more than 40 million new jobs by 2050.

Renewable energy plays an important role in strengthening communities and local economies. For example, it can provide an additional source of stable income for rural landowners and farmers, and significant tax revenue.

The tipping point has finally been reached: power from renewables is now cheaper than that from fossil fuels in two thirds of the world. Ongoing technological advances and scale have dropped the cost of renewable energy generation compared with fossil-based electricity generation. This is great news for energy consumers, and even better news for our planet.

Climate change is one of the greatest health threats of the 21st century, leading to 8.7 million deaths globally in 2018, according to new research. The burning of fossil fuels creates greenhouse gases as well as harmful particles that pollute our air and have the potential to cause serious health conditions, including asthma, bronchitis, and cancer. By contrast, renewable energy sources produce little to no air pollution.

Did you know that energy access is an area of great inequality? According to IRENA figures, over one billion people lack access to electricity, while a further one billion have an unreliable supply. For developing countries, renewable energy such as solar power has the potential to offer decentralised solutions that improve energy access and reliability, while creating local jobs.

Energy security, defined by the International Energy Agency as ‘the uninterrupted availability of energy sources at an affordable price’, is affected by a wide range of factors – from political instability to manipulation of energy supplies, as well as accidents and natural disasters. For countries that currently rely on imported fossil-based energy, which can fluctuate in price, renewable energy can promote a more sustainable and secure model of electricity supply.
