Despite its image as a dirty fuel, coal remains an economic choice for baseload power generation—and it can, in fact, have very low emissions.
When considering improvements to cooling towers, it's important to perform an economic analysis of the options.

These experimental and modeling techniques enable the rapid, cost-effective design and scale-up of biopharmaceutical manufacturing in an integrated fashion.
With the simplifying assumption that all of the noncondensable gases exit via the vapor stream, material balances and equilibrium calculations can be used to determine the compositions of the emissions streams leaving a control device.
As with previous emerging technologies, there have been uncertainties and concerns about the environmental and health risks associated with nanotechnology. This article reviews some of the ongoing efforts to better understand and characterize...
Infrastructure, biomass conversion, sources of biomass, and environmental and other impacts are some of the challenges facing the commercialization of biofuels.

Dynamic process modeling based on non-uniformly sampled data and multiple sampling runs, even for nonlinear systems, can be performed using spreadsheet implementations of the weighted-least-squares (WLSQ) and Runge-Kutta WLSQ methods.
Rising gas prices and climate uncertainty have thrust energy and environmental policy to the forefront of modern American politics.
