Renewable vs Nonrenewable Energy: What’s Driving the Transition?
Renewable energy now costs less than fossil fuels, making the transition all but inevitable. But are companies truly changing their operations for the sake of the planet or just buying into green initiatives to appear sustainable?

Was anything going to drive the energy transition more effectively than cold, hard cash? Inevitably, no.
When onshore wind energy costs between 37 and 86 dollars per megawatt/hour and solar power costs just 38 to 78 dollars per megawatt/hour, while gas peaking factories cost anywhere from 149 to 251 dollars per megawatt/hour, the cost/benefit ratio is abundantly clear.
It seems the market has spoken, and renewable energy makes the most sense, economically (outside of any logical environmental benefits). So, what changed?
Renewables Became Cheaper Than Fossil Fuels
Many renewables have become cost-competitive with conventional energy sources. The price of wind and solar energy has fallen to levels no one thought possible a few years ago.
According to Lazard’s 2025 publication of the Levelized Cost of Energy, onshore (37-86 dollars) and offshore wind (70-157 dollars) now undercut coal (71-173 dollars).
The costs have flipped so completely in the last decade that in some regions of the US, it’s now more cost-effective to build a new wind energy installation than continue to run existing coal-fired facilities.
According to many researchers, the revolution occurred because of a simple underlying principle. While renewables follow learning curves, fossil fuels don’t.
Fossil fuels are a commodity, subject to fluctuations in global supply and demand, geopolitical tensions, and the increasing cost of extraction, as scarcer reserves require greater levels of exploration.
Renewables, on the other hand, follow a very different trajectory. Every time we double renewable capacity, costs naturally decrease.
The principle is known as Wright's Law or the “learning curve effect”, and it’s been recorded across solar, wind, and battery technologies for decades.
Energy Storage Makes Them More Reliable
Arguments against making the transition to renewable energy often focus on the inconsistency of the power supply. Seasonal weather changes could make solar and wind power unreliable. Critics pointed to cloudy weeks, windless days and the mismatch between when the sun shines brightest (midday) and when the peak in demand for electricity occurs (usually evening).
However, innovations in energy storage, such as lithium-ion batteries, flow batteries, and grid-scale installation have all but settled the argument.
It’s now possible to use solar storage to capture and deliver excess energy during peak times. Battery systems ensure there’s always a reliable power source.
The price of solar energy paired with battery storage now ranges from 46 to 102 dollars per megawatt-hour, according to Lazard's report.
The price of wind energy with onshore wind storage (44 to 123 dollars) still comes in cheaper than all fossil fuels, too.
The Cost of Doing Nothing is High
The fossil fuels market has suffered a number of setbacks in recent years, from supply chain shocks to geopolitical crises and continued political instability in oil-rich nations.
It’s perhaps unsurprising then that 89% of UK businesses report profit losses from energy price volatility. As their operational margins are squeezed ever tighter, cheaper and more reliable energy supplies have become a strategic necessity.
On the flipside, renewables offer much greater price predictability. This is due to their source fuel (sun, wind) essentially being free. They’re not subject to political and social stability either, something no fossil fuel can claim. Also, considering Wright’s Law together with greater regulatory demand for renewable energy, the only way the cost should go is down.
2030 Targets Draw Closer
The climate crisis demanded strict targets, the deadlines for which draw ever closer. In the next 5 years, businesses will need to prove they’ve put the work in to meet them.
For many companies, this represents fewer than two budget cycles to meaningfully transform their operations - a timeline that demands immediate action.
The policy approaches driving the transition include:
- EU’s Net Zero Industry Act requires that 40% of net zero tech be manufactured in the EU by 2030, through the development of CO2 storage capacity. This represents a significant shift in European industrial policy, which now prioritises the production of climate technology alongside conventional manufacturing
- China’s 14th Five-Year Plan looks to reduce energy/emissions intensity through controls on coal consumption and optimising oil/gas use
- India’s National Action Plan on Climate Change, which looks to reduce greenhouse gases by expanding solar to 500 gigawatts by 2030 and improving energy efficiency across all industries
Inaction on renewables and climate-positive agendas will no longer fly. A fear of noncompliance and the business impact of not meeting even elective targets in the eyes of customers, regulators, and investors, also puts the transition into stark economic and business survival terms.
Governments Incentivise the Switch
There are a number of tax breaks and funding opportunities available, which have already successfully incentivised hundreds of businesses into undertaking renewable energy projects.
These include the US Inflation Reduction Act, for example, which targets a 40 per cent reduction in greenhouse gases by 2030 and offers substantial federal funding and tax incentives.
There’s also Japan’s Green Transformation Policy, which targets a 46 per cent reduction by 2030 and net zero by 2050 by offering investment and a carbon levy.
Outside of these major economies, many other nations offer compelling incentives to reduce barriers to entry in the renewables space.
So Why are Companies Buying Clean Energy But Not Reducing Consumption?
The plummeting cost of renewables has no doubt accelerated the transition to renewable energy use. Companies now claim to be purchasing 29 per cent of their energy from renewable sources.
However, of almost a thousand companies tracked by the CDP, only 10 per cent have set 100 per cent renewables targets, while less than 5 per cent have energy efficiency targets.
Here are the key reasons behind this disconnect:
1. It’s Easier
Renewable energy purchase agreements allow businesses to claim green energy credentials without necessarily changing the way they operate.
It’s done through the purchase of renewable energy certificates, which prove renewable energy has been generated from a particular source. However, a company can purchase several certificates and offset these against its fossil fuel consumption, claiming a more favourable ratio of renewable to non-renewable consumption.
It’s a much easier switch than real organisational change, such as retrofitting buildings (32% adoption according to UK data from PwC), upgrading equipment and processes (36%) or redesigning products to be less energy intensive (33%).
2. Reporting Doesn’t Capture the True Picture
Currently, reporting frameworks aren’t sophisticated enough to enforce real change in fossil fuel consumption. Many focus on renewable energy sourcing rather than the results of climate-positive organisational change as a key metric for “going green.”
As well as regulatory targets, businesses are also under pressure to prove their ethical and environmental credentials. Their continued market competitiveness relies on it. As such, it has become far more important to appear to investors and buyers that you’re a “green” company than it is to prove it.
Purchase agreements have made this possible, and businesses have naturally taken the path of least resistance to alleviate these external pressures.
3. Purchasing Offers More Certainty Than Reduction Measures
The predictability of renewable energy pricing has, in this instance, worked against it. The lack of renewable volatility means purchase agreements can offer guaranteed projected savings. So, when you buy renewable energy, you know exactly what you're getting.
Implementing efficiency projects, on the other hand, involves a level of uncertainty businesses would rather avoid. To prove the ROI and efficacy of these projects, they’d need to make projections and monitor things like usage, equipment performance, and process compliance.
Where Will We Be by 2033?
In less than a decade, the average 2033 target date for 100% renewables will be upon us.
By then, pricing logic dictates that renewable electricity should be the dominant source of power, with solar as the single largest source and massive battery storage enabling 24/7 clean power.
The economic case for renewables is irrefutable. Wind and solar consistently undercut fossil fuels on cost.
However, true progress in the transition to renewables demands that businesses move beyond convenient purchase agreements and towards genuine operational transformation.
Measurement frameworks will need to evolve to weed out the pretenders and prioritise a provable reduction in fossil fuel consumption over renewable energy sourcing claims.
The transition is happening, but the pace of real change relies on whether businesses will take the harder path that delivers lasting change or settle for the appearance of progress.
