Decoding the Seismic Shift in Renewable Energy: The Journey from 2010-2021

Published by firstgreen on

Over the past decade, the renewable energy landscape underwent a revolutionary transformation. Firstgreen Consulting, an industry leader in the renewable energy consulting domain, presents a comprehensive analysis of this dramatic change.

The Paradigm Shift in Renewable Energy Adoption

From 2010 to 2021, solar and wind power technologies have not only become more efficient but also significantly more affordable. What was once considered an expensive alternative has now robustly positioned itself as a direct competitor to fossil fuels? The relentless dedication of industry stakeholders, coupled with astute policy support, paved the way for a virtuous cycle. This cycle, characterized by increasing deployment, led to substantial technology improvements and subsequent cost reductions, propelling even more widespread adoption of these green technologies.

The Affirmative Data: A Glimpse into IRENA’s Findings

The International Renewable Energy Agency (IRENA) has been at the forefront of tracking these advancements. Their Renewable Cost Database sheds light on the transformative journey renewables have undertaken. The global weighted average Levelized Cost of Electricity (LCOE) for utility-scale solar PV projects saw a sharp decline of 13% in 2021 alone. Similarly, onshore wind projects experienced a 15% reduction in the same period. The offshore wind market, though still in its growth phase, added an astounding 21 GW capacity in 2021, with costs plummeting by 13% year-on-year.

Understanding LCOE: The Benchmark for Renewable’s Competitiveness

LCOE stands for the Levelized Cost of Electricity. This metric serves as a crucial barometer for determining the cost-effectiveness of energy sources over their lifecycle. The formula for LCOE is succinct:

LCOE= Total Lifetime Costs/ Total Electrical Energy Output


Total CAPEX$1,000,000
Annual OPEX$20,000
Project Lifespan25 years
Annual Electricity Output1,500 MWh
A typical solar plant data

Using the formula, the LCOE is calculated, offering a clear picture of the project’s cost-effectiveness over its operational life.

Challenges & the Path Forward

While the decade witnessed considerable cost reductions, challenges remain. 2021, for instance, experienced rising commodity prices and supply chain disruptions in several markets. These challenges impacted the installed costs of utility-scale solar PV in three of the top 25 global markets and seven for onshore wind.

However, the overall trajectory remains optimistic. The juxtaposition of renewables against traditional fossil fuel and nuclear options has seen renewables outperform. With utility-scale solar PV projects declining by 88%, and onshore and offshore wind by 68% and 60% respectively over the decade, the future seems promising.
