The Shift Towards Renewables is Well Underway
Around the world, countries are making ambitious commitments to transition their energy systems away from fossil fuels towards renewable sources like solar, wind and hydropower. This shift is well underway as the economics of renewable energy have improved dramatically in recent years, making clean sources increasingly competitive with traditional fossil fuels on cost. Several factors are driving this global energy transition.
Climate Change Concerns are rising
With climate change impacts intensifying and recent scientific reports warning of catastrophic consequences if global warming isn't curbed, there is mounting public and political pressure to rapidly decarbonize energy systems. Renewables offer a way to reduce greenhouse gas emissions from the power sector compared to coal and natural gas plants. Most countries have now committed to targets of getting a significant portion of their electricity from zero-carbon sources by 2030 or 2050 under the Paris Agreement. These efforts are central to the global Energy Transition, which aims to shift away from fossil fuels and towards sustainable, renewable energy solutions.
Falling Technology Costs Boost Renewables
Another major factor is the plummeting costs of renewable energy technologies like solar PV modules and wind turbines in the past decade. Utility-scale solar and onshore wind projects are now often the most economically attractive new power generation options in many parts of the world, undercutting new fossil fuel plants on cost without subsidies according to recent research. This is enabling a growing number of countries and states to pursue 100% renewable or carbon-free electricity goals that were previously not considered economically viable.
Energy Security Benefits of Domestic Renewables
Many countries and regions are also embracing distributed renewable energy sources like rooftop solar to boost energy security by diversifying their fuel mix and relying more on domestic energy resources that are not subject to fuel price volatility or geopolitical risks from foreign fuel imports. This growing self-sufficiency with homegrown renewable power is an added incentive for the energy transition.
Reduced Air Pollution from Renewables
A switch to renewables also yields major public health benefits by reducing air pollution from coal and gas-fired power plants. The World Health Organization estimates air pollution causes over 7 million premature deaths worldwide each year. Transitioning power generation and other applications to cleaner renewable sources can help countries make progress on reducing dangerous particulate matter, sulfur and nitrogen emissions that are linked to respiratory illnesses and premature mortality.
Corporate and Investor Support Accelerating Transition
Another driving force is growing momentum from large multinational corporations and investors. Many major companies have set targets to power all operations with 100% renewable electricity and have partnered with utilities on large renewable energy deals. Investors are also moving capital out of fossil fuel projects recognizing the long-term risks and moving it into renewable energy and associated infrastructure needed for the clean energy economy. This trend is accelerating the worldwide energy transition.
Progress despite Remaining Policy and Grid Integration Hurdles
Renewable deployment is surging globally, major policy and infrastructure challenges still remain in some regions to fully transition away from fossil fuels. Intermittent solar and wind power require strategies to dispatch electricity supply on around the clock which may necessitate more flexible gas plants, batteries or other storage, and transmission upgrades. Also, some governments still provide significant subsidies to fossil fuel industries that need reforming to give renewables a fair competition.
However, innovative solutions are emerging to overcome these challenges as costs continue declining. Countries achieving high renewable penetration levels like Denmark, Germany and Uruguay have demonstrated practical strategies to balance variable solar and wind power at a grid level. Advances in battery storage response programs, and wider regional grids are enabling renewables to supply base-load power reliably. While full global energy transition will take decades, the current pace of progress gives optimism that continued rapid growth of wind and solar deployment can help deliver emissions reductions aligned with the Paris Agreement goals.
The ongoing global shift from fossil fuels to renewable energy sources is being driven by mounting climate change concerns, rapidly falling technology costs, energy security and public health priorities. Major corporations and investors are also playing a key role in accelerating this important energy transition through procurement deals and shifts in capital allocation away from carbon-intensive projects. While policy and infrastructure challenges remain in some regions, countries achieving high renewable targets prove viable pathways exist to balance variable solar and wind power on electricity grids. Overall trends suggest the pace of the worldwide energy transition will only quicken in the coming decades as renewable technologies continue their cost-competitive growth trajectory. With ongoing progress, the world may potentially move even closer towards limiting global warming below the dangerous 1.5°C threshold.
