We focus on three key pillars of sustainable energy.

Energy efficiency – and demand response, its peak demand corollary – is commonly the lowest-cost, lowest-risk resource available for balancing supply and demand.

Yet it is often overlooked. According to the International Energy Agency, doing more with less through greater energy efficiency is not only the cheapest, but also the largest clean energy opportunity readily available. Fully half of the carbon reductions required to achieve current climate goals could come from improved energy productivity. That is three times as much as the next largest resource in the list: renewables.

At Dunsky, we help our clients to understand – and effectively exploit – the efficiency resource, whether for electricity, natural gas, oil, propane or other fuels. We assess the costs, savings, cost-effectiveness, and market opportunity for hundreds of options across every sector and market segment; we design market and regulatory strategies that lead to real-world adoption; and we evaluate the effectiveness of programs designed to this same end. In all cases, we bring market research, solid analytics and years of experience to the task.

    Program Manager, Energy Efficiency and Conservation

Renewable energy – and its enabler, storage – is critical to achieving a sustainable energy future. And though we have a long way to go, the transition to solar, wind, biomass, biofuels and other renewable energy resources, is now well underway.  Yet renewables are not a foregone conclusion – their ability to compete and grow market share can vary significantly across geographic regions, regulatory frameworks and government policies. Meanwhile, the need for non-grid storage solutions to address intermittency, is similarly variable.

We help our clients to assess opportunities for renewable energy – with an emphasis on demand-side (or “distributed”) renewable resources – and to develop programs and policies to support them effectively, and cost-efficiently. To this end, we use our experience with the full range of renewable energy and storage options – along with proprietary models that provide deep, location-specific insights – to determine what is needed to move the needle and achieve defined goals.

Our work includes assessing technical issues, resource potential and markets; designing voluntary programs (incentives, financing and others); building realistic business cases; and advising on regulatory mechanisms and policies.

  • Excellent work. Easy to read, and charts illustrate the points. It sets up the right conversation about our policy choices going forward to achieve our goals.

    Director, Texas Efficiency Programs

Moving people and things can use anywhere between a quarter and a third of all energy consumed in a given region – and it can emit the same share of greenhouse gases. Simply put, there can be no sustainable energy future without sustainable mobility. Thankfully, recent technological advances, combined with stricter government regulation and generational shifts in consumer preferences, are opening the door to an important evolution in the transportation industry.

At the nexus of energy and mobility, Dunsky is well-positioned to support our clients’ needs. Our emphasis is on the twin challenges of sustainable transportation: reducing energy demand (through improved fuel efficiency, an array of new “shared mobility” services and platforms, and non-vehicle alternatives), and shifting to alternative, low-carbon fuels (including, but not limited to, electric vehicles).

In all cases, we help our clients understand the options, build business cases, address regulatory barriers, and design both regulatory and market-based strategies aimed at accelerating the advent of sustainable mobility. Our work, which encompasses market, economic and technology facets, further extends to electricity storage, grid integration of electric vehicles, charging infrastructure, pricing and more.
