Rooftop Wind Energy Market Trends

Market Driver - Growing Environmental Awareness and Sustainability Initiatives

With the increasing threat of climate change, issues like global warming and rising sea levels have started troubling communities across the world. Urgent need to shift to renewable and cleaner sources of energy. This growing environmental consciousness among public as well as private entities has become one of the key drivers for exponential growth being witnessed in the rooftop wind energy market.

More companies and individuals are making efforts to reduce their carbon footprint and dependency on non-renewable energy sources. Many residential communities and commercial buildings are incorporating rooftop wind turbines in their design and construction to fulfill part of their energy needs through wind power.

Furthermore, some states and countries have enacted policies to disclose carbon footprint or energy source details of companies and buildings to nudge them towards becoming environment-friendly. This has encouraged 'Green Marketing' trend where companies now promote their eco-friendly steps including use of renewable sources like rooftop wind energy for gaining competitive edge in the rooftop wind energy market.

Market Driver - Government Incentives Promoting Renewable Energy Adoption

Government support through promotion policies and financial incentives has played a very significant role in spiking the adoption of rooftop wind energy systems across regions. In the United States, federal investment tax credit provides personal tax credit of 26% of the system cost and depreciation breaks for businesses installing renewable energy systems. Similarly, states like California and New York offer cash rebates up to $5000-6000 per residential wind turbine.

Countries like Germany, Spain and UK witnessed huge growth in their wind markets backed by lucrative FiT rates over past one decade. Meanwhile, nations in Asia Pacific region like India, China, Japan and South Korea are luring investments in renewable capacity additions including rooftop wind through measures like generation-based incentives.

countries are progressively strengthening their clean energy ambitions and continue supporting climate actions. Hence, the volume and effectiveness of incentives are expected to rise further providing a tremendous push to the global rooftop wind turbines market.

Market Challenge - Intermittent Wind Resources Causing Reliability Issues

One of the key challenges being faced by the rooftop wind energy market is the intermittent nature of wind resources. As wind power is highly variable and completely depends on the weather conditions, it can be difficult for utilities and grid operators to rely on rooftop wind energy.

When there is no wind, wind turbines do not generate any electricity which poses reliability concerns. Integrating variable wind power into the grid requires advanced forecasting tools to predict wind patterns and reserves to balance the grid during low wind periods.

The intermittent generation from rooftop wind turbines can cause imbalance in supply and demand. This frequently requires turning on backup power sources like natural gas plants on short notice to compensate for lulls in wind speed. The inability to dispatch power on demand increases the complexity in managing the energy assets. Maintaining grid stability and meeting constant demand is challenging with rooftop wind energy alone.

Market Opportunity - Integration of Hybrid Energy Systems (Solar and Wind)

The integration of hybrid energy systems combining rooftop solar and wind offers promising opportunities to address the intermittency issues of both these renewable resources. A hybrid solar-wind system helps provide a more consistent power output throughout the day compared to individual technologies.

When wind is low, solar power generation can make up for it during daytime and vice versa. This complementarity makes hybrid systems more dispatchable and better able to meet the varying electricity needs. They provide an optimal solution for buildings looking to tap into renewable self-generation. System owners can take advantage of net metering policies by offsetting more of their electricity usage.

Utilities see hybrid systems as a reliable off-grid alternative that eases grid constraints. Their modularity and scalability also appeal to a wider range of commercial and industrial adopters. Overall, hybrid energy holds significant potential to accelerate the deployment of decentralized renewable energy, boosting growth of the rooftop wind energy market.
