Cooler Planet
provides solar-energy tools that calculate return on investment, calculate break-even,
and account for incentives in the calculation. They also include tools that
allow you to see a map showing people in your area who used the solar calculators, an incentive map, and
a map of installations. Try the following tool from Cooler Planet:
Database of State Incentives for Renewable
Energy (DSIRE)
is a comprehensive source of information on state, local, utility, and
federal incentives and policies that promote renewable energy and energy
efficiency.
Energy Savers
provides ways to save energy and use clean, renewable technologies at home,
while driving, and at work.
Energy Star Home Improvement Toolbox
can help you save money and energy when remodeling, repairing, or improving your home.
FindSolar.Com Solar Estimator
provides a suite of interactive tools for researching the solar-power potential of your home or business; checking out federal, state, and local rebates and incentives; and researching the growth of solar
energy over the last decade.
NASA's Surface Meteorology and Solar Energy Data
is a renewable-energy resource website sponsored by NASA's Earth Science Enterprise Program that contains over 200 satellite-derived meteorological and solar-energy parameters, monthly averaged from 10 years of data, and data tables for particular locations.
National Oceanic and Atmospheric Administration (NOAA) Solar Calculator
finds the sunrise, sunset, solar noon, and solar position for any place on Earth.
National Renewable Energy Laboratory (NREL) Photovoltaic Area Calculator
uses assumptions about land-area requirements for photovoltaic systems to
estimate total land-area requirements for a system of a given size after
subtracting the portion of PV that can be placed on rooftops of buildings.
National Renewable Energy Laboratory (NREL) PVWATTS
Calculator
determines the energy production and cost savings of grid-connected photovoltaic
energy systems throughout the world. It allows homeowners, installers,
manufacturers, and researchers to easily develop estimates of the performance of
hypothetical photovoltaic installations.
National Renewable Energy Laboratory (NREL)
Renewable Energy Converter
performs basic calculations to covert electricity from renewable sources into
equivalent household energy needs and displaced emissions.
National Renewable Energy Laboratory (NREL) Renewable Energy Growth Calculator
projects future levels of renewable energy based on a starting value, growth
rate, and timeframe.
National Renewable Energy Laboratory (NREL) Renewable Resource Data Center (RReDC)
provides information on several types of renewable-energy resources in the United States in the form of publications, data, and maps.
National Renewable Energy Laboratory (NREL) Wind Farm Area Calculator
allows you to estimate land-area requirements for wind-power systems.
PVCalc
is a return-on-investment (ROI) calculator for photovoltaic (solar-power)
projects. You can freely specify all characteristics of the projects, including
different types of financing. The result is a cash-flow projection that is the
basis for four types of calculations.
RETScreen Renewable Energy Project Analysis Software
can be used to evaluate energy production, life-cycle costs, and reductions in greenhouse-gas emissions for various types of renewable-energy technologies.
RoofRay Solar-Potential Calculator
uses Google Maps to identify the location of a solar system to determine energy harvest. You find the house or building in question, draw a rough square
of where the system could go, select orientation and angle on the map, and the
system calculates harvest.
Simply Insulate
provides information on how to lower your energy usage by properly insulating
your home.
SunWize Solar Calculator
estimates the costs, savings, and payback of a solar system. |
