Hawaii Energy Symposium

Thank you for inviting me here today.


Hawaii primary energy consumption

As shown in the chart, Hawaii is heavily dependent on oil for energy.

(Source: EIA State Energy Data Report 1997, Table 83. Energy Consumption Estimates by Source, Selected Years 1960-1997, Hawaii.)


Economic Growth

This is how Shell expects world energy needs to grow and to be met over the next several decades. Note the projected decline in oil and natural gas and the increase in renewable energy, particularly solar.

Note that they've even got "surprise" there up at the top, to account for some kind of technological breakthrough.


Hawaii wind power resource

Wind

Hawaii has a significant wind resource.

The teal and green areas are class 3 and 4, which are fair to good resources with wind speeds that range from 14.3 to 16.8 mph.

The orange areas are excellent wind resources, with wind speeds measuring between 16.8 and 17.9 mph, mostly on the crests of ridges

The red areas have outstanding wind speeds, between 17.9 and 19.7 mph.

Solar

Almost 90% of the country receives between 6 and 8 kWh/m2 per day, plenty for effective use of PV.

All of Hawaii is in the 6 to 8 range.

A relatively small square just 5.25 miles on a side could generate the equivalent of all of your electricity use -- with PV operating at just 10% efficiency.

A square just 17.6 miles on a side could supply the equivalent of all of your energy use. It wouldn’t even have to be on land -- a floating square this size would do the trick, or an area broken up into a few thousand roof-size systems. You’re already on the way with 8,516 roofs.

The amount of sunlight available in a certain place each year allows us to calculate how much energy can be converted into electricity. There is approximately 2 to 3 megawatt hours per year of sunlight on each square meter of the U.S., depending on location. In total the U.S. receives 2.4X10 16 kWh of electricity per year, more than 10,000 times our annual energy use. Resource is average daily solar radiation per month, annual average for a 2-axis flat-plate PV system. On an average day, the U.S. receives approximately 5 to 9 kW for each square meter of exposed area. Las Vegas, for example, receives 9.7 kWh/m2; Boston receives approximately 5.3.

Using a distributed approach with systems installed on buildings, vacant land, and parking lots the same result could be achieved with PV in every state.


Photovoltaics are increasingly competitive.

Here's the rooftop photovoltaic system on the Mauna Lani hotel.

Photovoltaics are becoming increasingly cost competitive.

In 1980 the cost per kilowatt-hour (kWh) was about $1.00. Now (in 2000) electricity from photovoltaics costs about 20 cents per kWh. By 2005, it's expected to be about 10 cents.


Solar water heating is also increasingly cost competitive.

In partnership with the Hawaiian Electric Company, the U.S. Navy installed 136 solar water-heating systems on residences in its Moanalua Terrace family housing project. Each system offsets about 1.7 tons of carbon dioxide, 8.2 pounds of sulfur dioxide, and 11.2 pounds of nitrogen oxide every year. Funding to help pay for the project was provided by the U.S. Department of Energy Federal Energy Management Program, which helps agencies reduce their costs, increase energy efficiency, use renewable energy, and conserve water.


Picture of power lines

Power Lines...

Utilities spend millions of dollars to chop down trees and spray herbicides in order to build power lines. It costs billions more to maintain power lines and their rights of way.

Many renewable energy technologies can be placed on-site in sensitive areas where power lines would be inappropriate.


Old technology versus new technology

There is an ongoing shift from old technology to new technology.

The old technology was central station power, with power lines.

The new technologies include distributed generation, green power, and zero energy buildings.


Rebuild America and Build America

Right side: Hawaiian Electric Company (HECO) and its subsidiaries launched the Sun Power for Schools program in late 1996. The program is a green pricing program that forms a three-way partnership between the utilities, the State of Hawaii Department of Education, and electric utility customers. In July 1997, Sun Power for Schools made its first installation, a two-kilowatt PV system installed on the roof of the Kaimuki High School gymnasium. In addition to the Kaimuki High School installation, the Sun Power for Schools program has installed a number of other PV systems on schools on Oahu, Maui and Hawaii.

Whole-Building Approach

Rebuild America – 300 partnerships to date; Retrofits of 510 million sf; saving 10.8 trillion Btu and $170 million/year.

Build America – Industry-led, cost-shared program to use systems engineering to reduce energy use, construction time, and construction waste by as much as 50%.

Solar Buildings Vision

By the year 2020, there will be constructed, in the United States, a significant number of buildings that:

· meet their own energy needs by utilizing solar or other renewable resources,

· have no on-site or off-site carbon emissions,

· reduce utility peak electrical demand,

· optimize the health and productivity of their occupants, and

· provide energy security from natural disasters and extended power outages.


Zero Energy Buildings

The Opportunity:

Several DOE and electric utility energy efficiency programs carried out in the 1990s have demonstrated cost-effective new buildings with 60%–80% overall annual energy savings compared with energy-code compliant base case buildings. Continuing improvements in the energy performance of building enclosures, glazings, lighting systems, HVAC systems, controls, and office equipment can further reduce new building energy requirements. With reduced building loads, solar technologies can offer the opportunity to achieve "zero net annual energy use" in new buildings. In fact, some zero net energy (ZNE) buildings have already been completed; however, the challenge is to achieve cost-effective and affordable ZNE buildings. Clearly, widespread construction of ZNE buildings would also contribute significantly to U.S. economic and environmental health.

And here's the answer for transportation. (Just kidding.)

Millin Solar Roofs fundamentals

Million Solar Roofs Initiative

  • Announced by President Clinton, June 26, 1997, in address to United Nations Session on Environment and Development
  • Announcement of Million Solar Roofs by Energy Secretary Peña, June 27, 1997
  • White House directs agencies to prepare plans and information on programs they can use to support the Initiative
  • Made into a line item in FY99 Appropriations

Map of 48 partnerships across the U.S. Hawaii has four.

Million SOlar Roofs Accomplishments

2001 Action Plan


When choosing the best energy resource becomes the criteria, renewable energy will win easily. Poll after poll for nearly two decades now has shown a strong public preference for renewable energy.

MSR is a bellwether indicator of community support. We now have 48 MSR partners, pulled together in just 3 short years.

Partnerships are the heart of the MSR Initiative. DOE and the national labs help out with technical advice, a little seed money, and a network for sharing problems, solutions, and success stories so that each partnership can benefit from the collective experience.

  • We expect that over the next 20 years the world’s installed electricity capacity will double. Today that is about 3 million megawatts. That means another 3 million megawatts by 2020. That will be going to condition and light buildings, heat water, and run appliances that could be served by PV, solar thermal, or passive solar technologies.
  • Renewable energy does create jobs and economic growth, just like we said it would.
  • The number of states with renewable portfolio standards or systems benefits charges for renewable energy now stands at 27. That represents billions of dollars available for renewable energy development.
  • In addition to providing money to the economy through industry growth, it’s also saving us money, and even more importantly helping the environment.
  • The signs of change are becoming obvious. Over the next few years the nature of how consumers buy electricity will be changed radically by utility restructuring.
  • Consumers are learning more about where their power comes from and that they have choices.
  • Wind Powering America is getting strong support from farmers in the Midwest, who are realizing that leasing some of their land to harvest the wind is good for their rural economies.
  • Change and disruption are becoming the rule in the new economy, not the exception.
