Clean technology refers to any process, product, or service that reduces negative environmental impacts through significant energy efficiency improvements, the sustainable use of resources, or environmental protection activities. In the past decade, demand for clean technologies has grown at a significant rate and has driven the growth of billion-dollar markets. Such markets continue to rise at a substantial rate. The clean technology market has been driven by a merger of technological advancements resource constraints, and economic trends that positions clean technologies for sustained growth. TechInsights has performed a broad range of work relevant to the clean technology sector including photovoltaics, smart grid, batteries, and low-energy lighting. For example, we have analyzed the construction techniques of industrial solar cell panels and design decisions in hybrid/electrical vehicles and performed detailed evidence of use analysis in LED manufacturing.
