The greener, the cheaper

In the light of the event COP26 held in Glasgow at the beginning of this month, many new researches have been started regarding the climate change and transition to renewable energy. These researches are showing that many of the previous predictions and thesis were wrong.

Every research came to the same conclusion: the green energy is the way forward. The renewable energy costs have drastically fallen during the last five years and this is a trend that is unlikely to stop in the years to come. 

Furthermore, the prices of the fossil fuels have significantly increased since the start of the pandemic Covid-19. In various countries, further increase of prices regarding fossil fuels was already announced.

Research from Institute of New Economic Thinking at Oxford University shows that all predictions made before did not anticipate the improvement of the infrastructure included in production of green energy. 

Energy produced from the sun is great example of good improvement of renewable source of energy. At first, it was used for powering up satellites in space. When it was introduced into the sphere of powering up cities and countries, various predictions showed that it would stay pricey. This was not the case.

Solar power drastically decreased in price during the last years by introducing solar photovoltaic installations. PV installations improved the capacity of each solar panel and its effectivity. Also, it became cheaper and more reliable on the market.

The predictions made by International Energy Agency in their World Energy Outlook showed the decrease of only 2,6% in the decade after 2010. The upper limits of their prediction was only 6% and that was optimistic by their standards. The price decreased for 15% and is continuing to do so. 

Besides this, the effects the climate change with the transition to sustainable energy would be enormous. Less carbon-intensive supstances would be used, making the healing process that is needed for our planet much more faster and possible than it currently is.

International Energy Agency and some similar related organisations made a new forecast predicting that the improvement of this green energy is the most efficient and cost effective for supplementation of energy.

Recently, European Best Destination agency published a list of 20 green capitals of Europe. In their study they included the quality of air and water, local administration policies regarding pollution, percentage of people who cycle and public transports that emit zero CO2 to the atmosphere. The best ranked city in this research was Ljubljana, the capital of Slovenia. Before this research, the city was included six times in the Sustainable Destination Top 100 list. City of Ljubljana implemented various eco-conscious measures in the last decade and is continuously working to improve them even more.

Ljubljana’s city centre is car-free since 2008. There is bike-share scheme for locals and visitors which greatly decreased pollution and carbon footprint in the city. There is 200 kilometres of bike paths. Along with these policies, the city implemented green education in schools which resulted in 70% of the household waste separation. This city is primary example of eco- responsible policies and effectiveness of transition to the green sources of energy and environment.
