NREL Study Identifies the Opportunities and
A new report by the National Renewable Energy Laboratory (NREL) examines the types of clean energy technologies and the scale and pace of deployment needed to achieve 100% clean electricity, or a net-zero power grid, in the United States by 2035. This would be a major stepping stone to economy-wide decarbonization by 2050.

We Need a Renewable Energy Transition | Choosing Clean Energy
The world needs at least a nine-fold increase in renewable energy production to meet the Paris Agreement climate goals and much more to achieve net zero emissions by 2050. The rapid transition to renewable energy will be good for people and the planet. But the land-use footprint for this buildout will be large because renewable energy
Why is energy important?
Energy is at the heart of many of these Sustainable Development Goals – from expanding access to electricity, to improving clean cooking fuels, from reducing wasteful energy subsidies to curbing deadly air pollution that each year prematurely kills millions around the world.
Ten economic facts about electricity and the clean energy transition
Fully realizing the promise of the clean energy transition for U.S. economic growth, jobs, and prosperity will require developing solutions that remove the choke points created by the existing
4 Ways to Shift from Fossil Fuels to Clean Energy
Despite growing attention on clean energy, fossil fuels still account for 80 percent of global energy consumption and 75 percent of greenhouse gas emissions. Our fossil fuel-based energy system comes at a massive cost. Fossil fuels drive economic vulnerability, where countries and businesses are subject to volatile fuel prices; many are reliant on costly energy
Future of energy: Cleaner fossil fuels | Stanford Report
Is nuclear power clean energy? Scientists debate the pros and cons of nuclear power at an energy summit. Unseen gold. Stanford alumni aim to turn waste carbon into usable chemicals for industry.
3 Reasons Why Nuclear is Clean and Sustainable
Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a
The justice and equity implications of the clean energy transition
The costs and benefits of clean energy transitions will not be equally distributed. This Review of the literature on potential adverse impacts for specific communities highlights opportunities for
Making the clean energy transition work for everyone
The clean energy transition is already underway, but how do we make sure it happens in a manner that is affordable, sustainable, and fair for everyone? That was the overarching question at this year''s MIT Energy Conference, which took place March 11 and 12 in Boston and was titled "Short and Long: A Balanced Approach to the Energy

Renewable energy becomes cheaper in a bid to tackle climate
Renewable energy prices have fallen far more quickl than the industry anticipated, says a new report. And they are fast becoming cheaper than fossil fuels. A rapid transition to emissions-free ''green'' energy could save many trillions of dollars in energy costs - and help combat climate change.
Investment in clean energy this year is set to be twice the amount
Clean energy investment by oil and gas companies reached $30 billion in 2023, accounting for only 4% of the industry''s overall capital spending, according to the report. Meanwhile, coal investment continues to rise, with more than 50 gigawatts of unabated coal-fired power approved in 2023, the highest since 2015.
Clean energy is boosting economic growth – Analysis
Clean energy is moving towards centre stage in the global energy system – and as its importance rises, a new clean energy economy is emerging. Clean electricity accounted for around 80% of new capacity additions to the world''s electricity system in 2023, and electric vehicles for around one out of five cars sold globally.
These are the biggest hurdles on the path to clean energy
Innovation is often more about chasing after the shiny and new rather than improving on existing technologies. Nevertheless, the looming challenge of evolving from fossil fuels to renewable energy faces the immutable laws of physics and chemistry – and, ironically enough, environmental hurdles – that may be overlooked by today''s energy experts and policy
Setting the Record Straight About Renewable Energy
At the start of 2020, the clean energy sector employed about 3.4 million workers in the U.S., with much of the workforce concentrated in the energy efficiency industry. In 2019, clean energy jobs outnumbered jobs in the fossil fuel sector 3 to 1; across 42 states and the District of Columbia, the clean energy workforce was larger than that of
Let''s Come Clean: The Renewable Energy Transition Will Be
The reference to renewable energy driving up prices states clearly "these estimates do not account for the possibility of future cost reductions due to RPS-induced technological progress." In other words, if the trends of the last two decades continue and renewables get continually cheaper than the benefits could actually outweigh the costs
