This online engineering PDH course provides an introspective look into reducing CO2 emissions through comprehensive multi-sector and electric models.
The Inflation Reduction Act of 2022 (IRA) represents a significant legislative commitment to transform energy production and consumption, reduce the risks of climate change, improve environmental quality, and simultaneously spur investments that create economic opportunities. This course presents results from state-of-the-art multi-sector and electric sector models to assess how the IRA’s provisions reduce CO2 emissions.
This course is responsive to section 60107(5) of the Low Emissions Electricity Program within the IRA, which requires EPA to assess “... the reductions in greenhouse gas emissions that result from changes in domestic electricity generation and use that are anticipated to occur on an annual basis through fiscal year 2031.” This course primarily focuses on carbon dioxide (CO2) emissions because the vast majority of direct electric sector GHG emissions are from fossil fuel combustion and the increased use of clean electricity primarily offsets fossil fuel use in end-use sectors.
This 11 PDH online course is applicable to environmental and civil engineers, as well as others who are interested in gaining insight on CO2 emissions, and the solutions to reduce the negative effects of emissions.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Familiarizing with the emission reduction in multi-sector and electric sector models
- Gaining a general overview on the Inflation Reduction Act of 2022
- Familiarizing with the economy wide CO2 emissions analysis and results
- Learning about the key IRA provisions for the electric sector, the transportation sector, the building sector, and the industry
- Understanding sector analysis and results for electric sector, transportation sector, building sector and industry
- Learning about the different ways each sector can potentially contribute to air pollution and CO2 emissions

This engineering online PDH course contains a discussion of, and an example calculation of, the density and viscosity of a specified gas at a given temperature and pressure. In this course, the Redlich Kwong equation will be used for calculation of the compressibility factor of a gas. The Sutherland formula will be discussed and used in example calculations. Another method for calculating the viscosity of air at a specified temperature and pressure will also be presented and discussed.
The density and/or viscosity of a gas is often needed for some other calculation, such as pipe flow or heat exchanger calculations. If the gas temperature is high relative to its critical temperature and the gas pressure is low relative to its critical pressure, then it can be treated as an ideal gas and its density can be calculated at a specified temperature and pressure using the ideal gas law. If the density of a gas is needed at a temperature and pressure at which it cannot be treated as an ideal gas law, however, then the compressibility factor of the gas must be calculated and used in calculating its density. The Sutherland formula can be used to calculate the viscosity of a gas at a specified temperature and pressure if the Sutherland constants are available for the gas.
This 2 PDH online course is intended for chemical, mechanical and environmental engineers. After completing this course, you will have knowledge about methods for calculating the density and viscosity of a gas at specified temperature and pressure.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Ability to calculate the density of a gas of known molecular weight at a specified temperature and pressure at which the gas can be treated as an ideal gas
- Ability to calculate the compressibility factor for a gas at a specified temperature and pressure, using the Redlich-Kwong equation, if the molecular weight, critical temperature and critical pressure of the gas are known.
- Ability to calculate the density of a gas at a specified temperature and pressure for which the gas cannot be treated as an ideal gas, if the molecular weight, critical temperature and critical pressure of the gas are known.
- Ability to calculate the viscosity of a gas at a specified temperature if the Sutherland constant for the gas is known and the viscosity of the gas at a suitable reference temperature is known.
- Ability to calculate the viscosity of air at specified air temperature and pressure.

This online engineering PDH course provides guidance on building field capabilities in order to respond to the contamination of drinking water. The course also provides planning and implementation guidance, templates, customizable report forms, and other documentation for Sampling and Analysis (S&A) activities.
When performed in response to possible or credible drinking water contamination, the goal of Sampling and Analysis (S&A) is to confirm or rule out contamination through field and laboratory testing. It is one of the earliest utility-led activities initiated when the utility has activated its drinking water contamination response plan and continues throughout remediation and recovery if contamination is confirmed.

This online engineering PDH course will introduce you to methods for cleaning industrial water systems with chemicals. You will learn about pre-operational cleaning which is performed to prepare water-contacted metal surfaces to receive chemical treatment to provide protection from scale, corrosion and microbiological growth. You will also learn about remedial cleaning to restore water systems that have been fouled with scale, corrosion products and microbiological growth due to inadequate or ineffective water treatment. Examples of industrial water systems for which chemical cleaning are applicable are boilers, heat exchangers, cooling towers, and chillers.
Maintenance of an effective water treatment program is essential to minimize scale and corrosion problems in industrial water systems; however, scale and deposits will often form and require remedial cleaning. If not removed, these scale and water-caused deposits may impact the safety of operations personnel, interfere with heat transfer, and cause excessive damage to, or destruction of, the water-using equipment.
This 3 PDH online course is intended for industrial, chemical and mechanical engineers, as well as, maintenance personnel and construction professionals interested in learning about the use of chemicals for cleaning industrial water systems and equipment such as boilers, heat exchangers, cooling towers and chillers.
