Renewables on the Rise: Forecasted Growth in Global Power Generation Mix

Driven by various factors such as the need to combat climate change, reduce greenhouse gas emissions, and create a sustainable energy future, the demand for renewable and clean energy is rising. The transition to renewable energy does not only benefit the environment and public health but also contributes to economic growth, job creation, and energy access in both developed and developing regions. According to a report by Precedence Research, the global renewable energy market was valued at $970 billion in 2022. The market is expected to grow at a compound annual growth rate (CAGR) of 8.5% from 2023 to 2032 to reach a value of more than $2.18 trillion by the end of the forecast period. While the Asia-Pacific region was the largest market in 2022, North America is expected to be the fastest-growing region during the forecast period. China and the United States both rank high among the countries with the most clean energy production.

Growing concerns about climate change and environmental, social, and governance (ESG) factors are attracting significant investments towards renewable energy projects around the world. Moreover, the increasing industrialization and urbanization in developing countries are boosting the demand for electricity, leading to a higher adoption of renewable energy sources. As reported by the International Energy Agency (IEA), renewables share of the global power generation mix is expected to rise from 29% in 2022 to 35% in 2025, while the shares of coal and gas-fired power generation are expected to decline. Consequently, the CO2 intensity of global power generation is projected to continue decreasing in the upcoming years.

A Look at the Key Players in the Global Renewable Energy Industry

Now that we have discussed what’s going on in the global renewable energy market, let’s take a look at the 16 countries with the cleanest energy in the world.

Methodology

In this article, we have listed the 16 countries with the cleanest energy in the world. To collect data for our list, we consulted The International Renewable Energy Agency (IRENA). This database provided us with a list of countries and information on their renewable energy capacity as well as generation for the year 2021. We used the renewable energy share of electricity generation to narrow down our selection and rank the top 16 countries with the cleanest energy in the world.

The renewable energy share of electricity capacity is our secondary metric. In the case where multiple countries had the same renewable energy share of electricity generation, tie-breaking was done on the basis of renewable energy share of electricity capacity. The 16 countries with the cleanest energy in the world are listed below in ascending order.
