A new study released by the World Wide Fund for Nature (WWF) in Beijing shows that by 2050, clean and economical renewable energy can meet the global energy demand.

The report pointed out that the current energy model based on fossil fuels is not sustainable. Continuing this model will further increase the scarcity of energy. At the same time, it will need to obtain energy from more complex and volatile areas of environmental and political factors. This will eventually lead to higher and more volatile energy prices. The report said that it is foreseeable that energy security will continue to face challenges from energy supply disruptions, accidents and disputes.

What's more, emissions from fossil fuels account for about two-thirds of global GHG emissions, which is the biggest impact on climate change so far.

The report stated that more than 80% of the world's energy is currently derived from fossil fuels. By 2050, fossil fuels, nuclear energy and traditional bioenergy will be almost completely eliminated.

WWF Global Director James Lipp points out: "If we continue to rely on fossil fuels, we will face even more severe problems in energy prices, energy security and climate change in the future. This study provides a more promising and practical solution. Energy alternatives. In 40 years, the global prosperity and development will depend entirely on clean and economical renewable energy. By that time, the quality of people’s lives will also be greatly improved.”

The report shows that although the global population will increase in the next few decades, industrial expansion, aviation and tourism will increase energy consumption, but due to the improvement of energy efficiency, global energy demand in 2050 will still be 15% lower than in 2005. By then, 95% of global energy demand will come from renewable energy, which can meet the energy needs of electricity, transportation, industry and households.

To achieve this goal, the report proposes that the future will focus on improving energy efficiency in the construction, transportation, and industrial sectors, as well as strengthening renewable energy generation and smart grid transmission control to meet the increasing energy demand.

The report also proposes that by increasing energy efficiency and reducing fuel costs, by 2050, the annual energy use cost can save nearly 4 trillion euros compared with the current model. Prior to this, it was necessary to substantially increase capital investment to install large-scale renewable energy power generation equipment and modernize the power grid.

In fact, some major developing countries have demonstrated strong confidence in renewable energy prospects. At the climate conference in Copenhagen, China promised that by 2020 the carbon emissions per unit of gross domestic product (GDP) will fall by 40% to 45% compared to 2005. During the “11th Five-Year Plan” period (2006-2010), China’s energy consumption per unit of GDP decreased by 19.06%, basically reaching the goal of a 20% reduction.

An energy expert from the National Development and Reform Commission believes that China is still in the process of industrialization and needs a lot of steel, cement, and building materials. This goal is a very big pressure for China. In the process of industrialization, no country’s energy consumption has declined, and China has taken the lead in combating climate change. Hou Yanli, director of the WWF (China) Climate and Energy Project, said: "China is vigorously developing renewable energy and improving energy efficiency, showing a good momentum."

This energy report was jointly developed by WWF and energy consulting agency Ecofys and it took two years to complete.
