Green Energy Costs to 2035: Prices & Trends
Green Energy Costs to 2035: Why Solar and Wind May Rise While Batteries Fall
The global renewable energy revolution is accelerating. Governments, corporations, and households are investing billions in green energy systems. Yet a paradox is emerging: while the cost of generating solar power and wind energy may increase in the coming decade, battery storage prices are projected to decline significantly. Why is this happening? And what will it mean for consumers and investors by 2035?
This evergreen analysis explores the economic forces shaping energy markets, provides price forecasts in U.S. dollars, and explains how global trends could redefine the cost of clean electricity.
Why Green Energy Became So Affordable
Over the past 15 years, renewable technologies have experienced dramatic cost reductions. According to the International Renewable Energy Agency (IRENA), global weighted-average costs of solar photovoltaic electricity dropped by nearly 90% between 2010 and 2022.
Key reasons included:
- Mass production of solar panels
- Technological efficiency improvements
- Lower financing costs
- Government subsidies and tax incentives
- Economies of scale in large wind farms
As a result, solar and wind became the cheapest sources of new electricity generation in many regions.
Why Renewable Energy May Get More Expensive
Despite long-term efficiency gains, several structural factors could push prices upward toward 2035.
1. Raw Material Costs
Solar panels require silicon, silver, and aluminum. Wind turbines depend on steel, copper, and rare earth elements. As global demand rises, supply chain constraints can increase material prices.
2. Grid Infrastructure Upgrades
Integrating intermittent renewable energy requires major grid modernization. Transmission expansion projects in the United States and Europe cost billions of dollars annually.
3. Higher Interest Rates
Clean energy projects are capital-intensive. Rising global interest rates increase financing costs, which can directly affect electricity prices.
4. Labor and Land Costs
Land availability, environmental permitting, and skilled labor shortages also contribute to rising installation expenses.
Solar Power Price Forecast to 2035 (USD)
According to analysis from the BloombergNEF Energy Transition Outlook, solar power remains cost-competitive but may see moderate price stabilization or slight increases due to system-level costs.
| Year | Average Utility-Scale Solar LCOE (USD per MWh) |
|---|---|
| 2025 | $30 – $45 |
| 2030 | $35 – $50 |
| 2035 | $40 – $55 |
The modest increase reflects grid integration and storage requirements rather than panel costs alone.
Wind Energy Price Forecast to 2035 (USD)
According to data published by the International Energy Agency (IEA), wind projects face rising turbine and installation costs.
| Year | Onshore Wind LCOE (USD per MWh) |
|---|---|
| 2025 | $35 – $55 |
| 2030 | $40 – $60 |
| 2035 | $45 – $65 |
Offshore wind remains more expensive, potentially exceeding $80–$120 per MWh in certain markets.
Why Battery Storage Is Becoming Cheaper
In contrast to generation costs, battery prices are expected to decline sharply. According to the BloombergNEF battery price survey, lithium-ion battery pack prices fell to near $139 per kWh in recent years.
Drivers of declining battery costs include:
- Scaling electric vehicle production
- Advances in lithium iron phosphate (LFP) chemistry
- Improved energy density
- Manufacturing automation
Battery Storage Price Forecast to 2035 (USD)
| Year | Average Battery Pack Price (USD per kWh) |
|---|---|
| 2025 | $120 – $140 |
| 2030 | $80 – $100 |
| 2035 | $60 – $75 |
By 2035, battery storage could cost nearly half of today’s levels, making renewable energy systems more stable and reliable.
How Cheaper Batteries Offset Higher Generation Costs
While solar power and wind energy installation costs may rise modestly, declining battery storage costs can balance overall system expenses.
For example:
- Residential solar + battery system (2025): $18,000 – $25,000
- Projected cost in 2035: $14,000 – $20,000
This means consumers may still pay less for complete renewable systems despite moderate increases in generation costs.
Global Investment Trends
Global investment in renewable energy exceeded $500 billion annually according to BloombergNEF. Governments are implementing climate policies that further stimulate demand.
Regions leading the transition include:
- United States
- European Union
- China
- India
Key Factors That Will Shape Prices to 2035
- Technological innovation
- Critical mineral supply chains
- Geopolitical stability
- Climate policy frameworks
- Energy storage breakthroughs
What This Means for Consumers
Homeowners considering green energy systems should focus not only on panel prices but also on total system integration costs. As battery storage becomes cheaper, the economics of self-consumption improve significantly.
For investors, renewable energy remains one of the fastest-growing sectors globally. Long-term demand for clean electricity is expected to rise due to electrification of transport and industry.
Conclusion: The 2035 Energy Landscape
By 2035, renewable energy will likely remain the backbone of global electricity generation. Although certain system-level costs may rise due to infrastructure and materials, battery storage price declines could offset these increases.
The clean energy transition is not just about cheaper solar panels or turbines. It is about an integrated system combining renewable energy, smart grids, and affordable battery storage.
