The global shift towards renewable energy
As we go past 2026, renewable energy sources will have advanced significantly on a global scale due to the increasing need for green solutions as far as the environment is concerned. The reason is that it will be the most important source of electrical power in the world due to its affordability.
By 2030, the amount of renewable energy will almost triple, with solar and wind energy leading the growth. This change is very important, as renewables could provide more than 80% of the world’s energy by 2050 and reduce up to 70% of carbon emissions from energy use.
Top countries driving the renewable energy revolution
The leading nations in terms of renewable energy are countries such as China, the USA and India, while countries such as Iceland, Norway, Denmark and Germany tops the list for having a high percentage of renewable energy production, almost approaching 100%.
China is leading the race with more than 31% of the world's renewable energy production at 3,399 TWh, the USA follows in second place with a 10.9% share of global renewable energy production, followed by Brazil for its high hydro energy production.
Seven countries - Albania, Bhutan, Nepal, Paraguay, Iceland, Ethiopia and Democratic Republic of Congo—generate over 99.7% of electricity from renewables, mostly hydro and geothermal. Denmark sources 88% from renewables which are led by wind, whereas Germany installs 100,000 solar panels daily.
Norway’s Renewable Energy System: A Global Benchmark
Norway is known globally as one of the most efficient countries in the use of renewable energy because it generates approximately 85-95% of its energy needs from hydro power and also rapidly increasing its potential for wind energy due to strong government support and the use of advanced technologies.
The geographical location of the country allows using hydro energy at a high level and water reservoirs are considered energy reserves. The company Statkraft intends to invest up to €6 billion by 2030 into improving the current facilities and increasing the capacity of hydroelectric plants by 20% or more.
Wind power generation is considered the fastest developing source of energy in Norway, where there are plans for adding up to 18 TWh of production until 2030, and up to 30 GW by 2040 of offshore production with Norway being a leader in the area with the project Hywind Tampen.
Norway is the leader in electric vehicles, which makes up about 90% of cars sold annually, resulting in a growing need for electricity. At the same time, Norway is able to continue being an energy exporter not only oil and gas but also electricity to Europe via NordLink.
Renewable Energy: The Backbone of India’s Future Economy
The adoption of renewable energy will be vital in enhancing economic development and energy security in India without exposing itself to unnecessary hazards of importing fossil fuels. The cost incurred by India for importing oil and natural gas was approximately $140 billion in 2025. Furthermore, 85% of India's consumption of crude oil is sourced from imports, thus requiring renewable energy resources.
The country leads in terms of embracing renewable energy technologies and aims at producing 500 GW of power from energy sources that are non-fossil fuel based by 2030. The embrace of renewable energy technologies is crucial, both for environmental conservation and economic stability.
One of the major contributors to this weakness is the Strait of Hormuz, a narrow waterway used by nearly 20% of the world’s oil trade. India’s exposure to this chokepoint is considerable, with an estimated 35–40% of its crude imports passing through the strait, largely from producers such as Saudi Arabia, Iraq, Kuwait and the United Arab Emirates.
China’s Strategic Energy Leadership and Its Long-Term Vision
Thanks to the forward-thinking energy policy of China since 2003, the country has been able to emerge as a world leader in renewables, electric vehicles and electrification and thereby became less reliant on oil supply lines.
In his speech, "Malacca Dilemma," Premier Hu Jintao, back in 2003, mentioned that about 70% of the oil supplies were passing via the Strait of Malacca, at a rate of 24 million barrels per day and Hormuz, at a rate of 21 million barrels per day. As a result, China began investing in renewable energy, high-speed rails, EVs and electric trucks, therefore becoming the world leader in the use of solar and wind power.
How Sustainable Is Australia’s Current Energy Strategy?
The Australian policy of 2004 relied upon market-based fossil fuels, which made the country vulnerable to imports as well as refineries.
The white paper of 2004 called "Securing Australia's Energy Future" focused more on market-based energy despite its warning about uneconomic refineries and instead favoured fossil fuel over diversification.
Australia is highly dependent upon diesel as it accounts to the highest consumption per capita in the world, dependent on oil from Hormuz and has even recently had a refinery fire in Geelong.
Global Pioneers of Fully Renewable Energy Systems
A number of nations utilize large supplies of natural resources including river water, geothermal power and wind power to get most of their electricity through renewable sources and ensure energy independence and minimal carbon footprints.
Albania, Bhutan, Nepal, Paraguay, Ethiopia, Democratic Republic of Congo and Iceland meet over 99.7% of their electrical power requirements through renewable sources mostly hydroelectricity based on major rivers and geographical features. Paraguay exports excess power produced at Itaipu Power Station, while Iceland gets 70% hydro and 30% geothermal electricity.
Who Are the Near 100% Renewable Energy Leaders?
Besides nations which have attained close to 100% renewable energy, there are quite a few nations that have achieved remarkably high percentages of clean electricity production.
In Norway, about 98.6% of electricity is generated by hydropower, while a minor percentage of electricity is produced by wind energy. Additionally, it also supplies a considerable amount of clean energy into other European nations.
Uruguay is one country which has rapidly transformed itself into a clean electricity-producing nation. Now Uruguay produces over 99% of its electricity through a mix of hydropower, wind energy, bio-energy and solar energy.
Denmark is one of the best examples of wind energy across the globe. About 89.6% of its electricity comes from renewable energy, with a significant portion being wind energy.
