The Global Electricity Review 2025 highlights


Global energy think tank EMBER released its Global Electricity Review in April this year. The review highlighted some interesting trends in the generation of electricity from low-carbon sources. You can read the full report on the EMBER website: https://ember-energy.org/latest-insights/global-electricity-review-2025/ but here are a few key take-aways from our perspective.


Renewables Supplied a Record 32% of Global Electricity in 2024

Renewable energy sources—primarily wind, hydro, and solar—provided 32% of global electricity in 2024, up from 30% in 2023. This growth occurred alongside a 4% rise in global electricity demand, driven by increased cooling needs during heatwaves and expanding usage by data centers, AI systems, electric vehicles, and heat pumps.


Clean Energy Growth Outpaces Electricity Demand

In 2024, clean energy met over 40% of global electricity demand for the first time since the 1940s, according to Ember. This significant milestone was driven primarily by a rapid expansion in solar power, which has doubled in capacity over the past three years and has been the fastest-growing energy source globally for two decades. Despite its rapid growth, solar power accounted for nearly 7% of global electricity in 2024, and wind contributed just over 8%. Hydroelectric power remains the largest source among renewables, supplying 14% of global electricity. The report also highlights that clean energy sources, including nuclear and bioenergy, are growing at a rate that surpasses the overall growth in electricity demand, potentially displacing fossil fuels in the energy mix.


Asia Leads in Clean Energy Transition Momentum

In early 2025, Asia has significantly outpaced Europe and the U.S. in transitioning to clean energy. Countries like China, India, South Korea, and Japan have reduced fossil fuel usage and increased clean power output, unlike their Western counterparts. For instance, South Korea cut fossil fuel electricity generation by 15%, and India saw a 26% rise in clean electricity production compared to January 2024. Conversely, Europe and the U.S. have increased fossil fuel-fired power due to weak wind power output and high electricity demand.


The report underlines the rapid increase in growth across solar and wind —especially in fast-growing markets like China, India, and parts of Southeast Asia—this is realised in the increase in competition for Installation and maintenance technicians, Grid engineers and electricians and Manufacturing workers (for solar panels, batteries, wind turbine components).

How a mix of market knowledge, established networks and employer branding can help you find your perfect candidate.

The renewable energy sector is it a pivotal point —solar, wind, hydrogen, and battery storage are expanding faster than ever. But here’s the challenge: the competition for top talent is just as fierce as the race to net zero. Companies that want to attract and keep the best people need to do more than offer competitive salaries—they need to build a strong employer brand. So, why does employer branding matter so much in renewables? And what can companies do to stand out? Let’s dive in. The Talent Scramble in Renewables Renewable energy jobs are booming, but there’s a skills gap. Engineers, project managers, data analysts, and sustainability experts are in high demand, and many companies are fishing in the same talent pool. Without a compelling employer brand, businesses risk losing top candidates to competitors—or even to other industries. A strong employer brand isn’t just about looking good on LinkedIn. It’s about: Attracting the right people: Candidates are drawn to companies that align with their values, offer meaningful work, and provide clear career growth opportunities. Retaining top talent: Employees are more likely to stay if they feel connected to the company’s mission, culture, and leadership. Building credibility: A great employer brand boosts a company’s reputation, making it easier to secure investment, customers, and strategic partnerships. What Makes a Strong Employer Brand in Renewables? Here’s what renewable energy companies need to focus on to build a brand that attracts and retains top talent: 1. Purpose-Driven Culture People want to work for companies that are making a difference. Renewables have an edge here—sustainability is already baked into the mission. But it’s not enough to just talk about saving the planet. Companies need to: Clearly communicate their vision and impact. Show how employees contribute to that mission. Celebrate real-world success stories. 2. Competitive and Transparent Pay The renewable energy sector is competing with oil and gas, tech, and other industries for skilled professionals. Offering competitive salaries is crucial, but transparency is just as important. Candidates want to know: Salary ranges upfront. Opportunities for performance-based incentives. Clear pathways for promotions and raises. 3. Career Development and Upskilling With rapid advancements in renewable tech, employees want to know they’ll keep growing. Companies should invest in: Training programs and certifications. Internal mentorship opportunities. Clear career progression paths. 4. A Strong Online Presence Job seekers research companies before applying. A well-crafted LinkedIn page, engaging company website, and positive employee reviews on sites like Glassdoor can make all the difference. Companies should: Share employee success stories. Highlight workplace culture and values. Actively engage with followers and potential hires. 5. Inclusive and Diverse Workplaces Diversity isn’t just a buzzword—it’s a competitive advantage. The best employer brands actively promote: Inclusive hiring practices. Equal opportunities for leadership roles. A workplace culture that welcomes different perspectives.
