What s the problem why act quickly

What’s the Problem? Why Act Quickly?

Air pollution mortality is one of five leading causes of death worldwide

Global temperatures are rising faster than during deglaciation at end of last ice age; Arctic sea ice is decreasing quickly

Higher population and growing energy demand will result in higher energy prices and worse air pollution and climate problems over time.

Mark a ruffalo water defense marco krapels rabobank

Why Not Nuclear?

9-25 times more pollution per kWh than wind from mining & refining uranium and using fossil fuels for electricity during the 11-19 years to permit (6-10 y) and construct (4-9 y) nuclear plant compared with 2-5 years for a wind or solar farm

Risk of meltdown (1.5% of all nuclear reactors to date have melted)

Risk of nuclear weapons proliferation

Unresolved waste issues


Mark a ruffalo water defense marco krapels rabobank

Why Not Clean Coal

(With Carbon Capture)?

50 times more CO2 emissions per kWh than wind

150 times more air pollutant emissions per kWh than wind

Requires 25% more energy, thus 25% more coal mining and transport and traditional pollution than normal coal.


Mark a ruffalo water defense marco krapels rabobank

Why Not Ethanol?

Corn and cellulosic E85 cause same or higher air pollution as gasoline

Corn E85: 90-200% of CO2 emissions of gasoline

Cellulosic E85: 50-150% of CO2 emissions of gasoline

Wind-BEVs: <1% of CO2 emissions as gasoline

Enormous land use and water requirements


Mark a ruffalo water defense marco krapels rabobank

Why Not Natural Gas?

50-70 times more CO2 and air pollution emissions per kWh than wind

Hydrofrackingcauses land and water supply degradation

Methane leaks a leading cause of Arctic ice loss over next 20 years

End Use Power Demand For All Purposes

In these tests, California electricity was obtained from WWS for 99.8% of all hours in 2005, 2006. Can oversize WWS capacity, use demand-response, forecast weather, use more CSP to reduce natural gas backup more.

Summary of Plan to Power World with WWS

  • Converting to Wind, Water, & Sun (WWS) and electricity/H2 will reduce global power demand by ~32%

  • Eliminates 2.5-3 million air pollution deaths/year

  • Eliminates global warming, provides energy stability

  • 2030 electricity cost 4-10¢/kWh for most, 8-13 for some WWS ,

  • vs. fossil-fuel direct+externality cost ~13.5¢/kWh

  • Additional long-distance transmission (1200-2000 km) ~1¢/kWh


Mark a ruffalo water defense marco krapels rabobank

Summary of Plan to Power World with WWS

Requires only 0.4% more of world land for footprint; 0.6% for spacing (vs. 40% of world land for cropland and pasture)

Multiple methods of addressing WWS variability.

Materials are not limits although recycling may be needed.

Barriers : up-front costs, transmission needs, lobbying, politics.

Scientific conclusion:

WWS can power the USA


Mark a ruffalo water defense marco krapels rabobank

Businesses need energy price stability

and predictability.  Oil and gas can’t

provide that. Solar, wind and water can.


Mark a ruffalo water defense marco krapels rabobank

There's plenty of it:  1 hour of the sun's energy can power the planet for a year.

Google definition of Fossil:  An antiquated

or stubbornly unchanging person or thing.


Mark a ruffalo water defense marco krapels rabobank

Over the last 100 years, trillions of dollar have been invested in building a fossil fuel dependent energy infrastructure.

Since 1960 the oil and gas industry has received $400 billion in US subsidies

 They are still receiving

$4 billion per year…

Committment to Renewable Energy: Direct Financing - Lakeside Dairy

Key Facts:

Location: Hanford, CA (Central Valley)

System Size: 887 kW DC

Configuration: Single-axis tracker

Expected first year energy production: 1,716,851 kWh

Utility Offset: Expected to replace 78% of utility power use at meter

Power Equivalency: Solar production equal to 243 homes in California

Lakeside Dairy is a family-run dairy operation with 6,300 head of cattle and

a custom farming business. The recent volatility in milk prices has

underlined the importance of hedging costs. The solar energy system

enables Lakeside to hedge against long run increases in utility power rates,

improving the client’s business and creditworthiness.

Committment to Renewable Energy: Direct Financing - Castle Rock

Key Facts:

Location: Delano, CA (Central Valley)

System Size: 1,184 kW DC

Configuration: Fixed ground mount

Expected first year energy production: 1,771,507 kWh

Utility Offset: Expected to replace 69% of utility power use

Power Equivalency: Solar production equal to 251 homes in California

Castle Rock Vineyards is one of the world’s largest table grape growers. Many of Castle Rock’s European clients inquire about sustainability, making green technology and practices an integral part of Castle Rock’s business. Their solar energy system, financed by Rabobank, powers their cold storage facility. Rabobank structured the loan with a customized amortized loan to match the seasonality of solar energy production and associated state incentives. The value of avoided utility payments, combined with federal and state incentives, enables Castle Rock to generate net positive cash flow on a quarterly basis after loan payments. After the loan is paid off, Castle Rock’s savings will increase correspondingly. As utility electricity prices rise over time, their annual savings will increase.

Committment to Renewable Energy – Main Financial Drivers

  • Main Financial Subsidies/Benefits from Ownership of a Renewable Energy Project

  • 30% Investment Tax Credit or Cash Grant

    • The American Recovery and Reinvestment Act (ARRA) of 2009 allows eligible taxpayers to take an investment tax credit (ITC) or to receive a cash grant from the U.S. Treasury Department.

    • The grant in lieu of tax credit option falls under section 1603 of the ARRA and is only available to systems where construction began prior to December 31, 2011.

  • Depreciation Benefits

    • Business owned systems may be eligible for MACRS 5-year Accelerated Depreciation

    • The Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 allows for 50% bonus depreciation in 2012 for projects placed in service for by December 31, 2012

      • "Bonus Depreciation" means acceleration of the otherwise applicable depreciation (not "more" depreciation, but "sooner" depreciation)

    • Depreciable basis of a Renewable Energy System is 85% of project cost (the depreciable basis is reduced by one-half of the tax credit total or 15%)

    • Net Depreciation Impact: Assuming a 35% Federal Tax Rate, depreciation could account for approximately 30% of the cost of the renewable energy project

  • State Incentives

    • Based on the production of the renewable energy system

    • Incentives varies by state/utility; may account to 5%-10% of the total cost of the project
