Disrupting the Status Quo…  Thinking Out of the Box

By Malcolm Metcalfe on May 4, 2017 8:58:22 AM

A few days ago, I listened to a group of environmentalists on the evening news protesting a plan to build a new bridge that would solve traffic congestion and make it easier for people get in and out of a local large city. The protestors wanted the money spent instead on public transit, claiming that this options had not even been examined, and arguing that their solution would solve the transportation problem without requiring construction of new infrastructure.

I looked more closely at both alternatives. The government and the consultants retained to propose solutions to the problem had advanced several standard options, all of which revolved around either a bridge or a tunnel, while the environmentalists had extended the options by one – adding public transit as a means to achieve a similar result.

This seemed logical until I started thinking about the need to add one other criteria to the equation: the need to reduce carbon emissions.

Energy Policies Aimed at 100% Renewables are Well Intended… But Perhaps Misguided…

By Enbala on Feb 17, 2017 9:48:51 AM

Cities around the world, including 22 cities in the United States and a growing number in Canada have pledged to go 100% renewable. It’s a noble, collaborative effort to be the cleanest, most environmentally sustainable cities on the planet, with an ultimate and cumulative end goal of each city doing its part to reduce worldwide carbon emissions.

Many cities that have made the pledge don’t yet have a route to an all-renewables, carbon-free destination. Some don’t have ownership of their electricity providers and thus have little or no influence over power fuel sources. Others depend today on energy sources that are based almost entirely on fossil fuel, making the renewables transition particularly difficult.  Still others are dealing with high permitting costs for popular renewable options like rooftop solar, as well with other regulatory obstacles. Technologically, anyone switching to a renewables-based grid must, by default, deal with the intermittency and reliability issues imposed by wind and solar. Even hydro electric energy is generally limited by the amount of water flowing in rivers, a quantity that can vary significantly over time.

A broader question, however, is why a fully renewable grid is more desirable than any other combination of zero-carbon energy sources. And what the overall effort and cost would be to decarbonize via that pathway alone.

Transitioning the Energy Economy: One Very Logical Approach

By Malcolm Metcalfe on Jan 18, 2017 12:58:53 PM

Canada’s Prime Minister made a statement recently that caused some problems in parts of Canada. The comment -- “We need to phase out fossil fuel…” -- has raised strong opposition in Alberta, the province that has largely powered the Canadian economy in recent years, based almost entirely on fossil fuel.

Confusing messages are being delivered. Science has told us that we need to REDUCE EMISSIONS. Emissions can be reduced in two ways: use less fuel or use it more efficiently. Politicians, almost uniformly, seem to have decided that the solution is to eliminate fossil fuel and replace it with renewable energy. This transition may be a lot more difficult, time consuming and costly than it may initially appear.

Ontario is perhaps one good example. A large expenditure in wind capacity seems linked to very high electricity prices in the very areas where the wind turbines are located. Germany has seen dramatic increases in electricity costs as the country has increased its use of solar and wind capacity to generate electricity.

The electric system seems to be a scapegoat, largely because in the US, it is the single largest source of emissions. Yet it delivers only a fraction of the energy needed to meet the total energy required.

Surely there is a better way to reduce emissions without producing disruptive cost increases and heavy restrictions on supply.

CREATIVE FINANCING OPTIONS OPENS THE DER DOOR TO SMALLER BUSINESS CUSTOMERS

We all know the big guys – large commercial and industrial (C&I) customers – have been able to participate in wholesale markets thought demand-management programs for years. Now, small C&I customers are gaining this opportunity, too.

What gives? The financing.

Distributed Energy Resources: The Energy Efficiency Story

By Ginger Juhl on Oct 5, 2016 8:30:00 AM

Today, October 5, is the inaugural Energy Efficiency Day 2016, and the perfect time to talk about what we are doing - in conjunction with our customers - to reduce traditional energy consumption and make the world a better place for ourselves, our children and our children’s children.

Energy Efficiency Day is a collaborative effort of regional and national organizations working to promote energy efficiency, including many that we strongly support. This includes the American Council for an Energy-Efficient Economy (ACEEE), Advanced Energy Economy, the Regional Energy Efficiency Organizations, Appliance Standards Awareness Project, E4TheFuture, Natural Resources Defense Council, and a very long list of cities, utilities, universities, associations and companies like ours who share a common mission with sustainability at its core. You’ll see most of us writing, tweeting and otherwise sharing our energy efficiency stories today – stories about using better technology and practices so that less energy is consumed to accomplish the same tasks, while continuing to keep homes and businesses comfortable.

Capturing the Full Benefits of Demand Flexibility

By Ginger Juhl on Aug 11, 2016 9:00:00 AM

This blog was co-authored by Enbala and the Rocky Mountain Institute (RMI). Enbala extends its heartfelt thanks to the Institute for the insights and effort that went into creating this piece. 

INTRODUCTION:

Demand flexibility - allowing household devices like HVAC systems and smart appliances to interact with the electric grid in response to real-time price changes - can save customers money and lower the overall cost of electricity. The Rocky Mountain Institute's recent paper, The Economics of Demand Flexibility, analyzed the economics of making common household loads controllable and responsive to electricity price signals. The Institute found that just making two devices flexible, i.e., smart thermostats that could flex an HVAC system’s output up or down by 2 degrees and smart water heaters that could change the timing of water heating, could lower system-wide peak demand by eight percent and save $10–15 billion in costs to the grid annually.
