2013
Surface renewal is a micrometeorological method that is being used increasingly to determine energy fluxes, but its technical complexity makes it inaccessible to a broad audience. We describe the steps needed to set up and calibrate a surface renewal field station, to acquire and process data, and to correctly interpret results.

2016
In this study, a protocol was developed to produce good quality pellets using a flat die pellet mill at reduced specific energy consumption testing high-moisture corn stover and a starch based binder. The results indicated that adding a corn starch binder improved the pellet durability, reduced percent fines and decreased specific energy consumption.

What is Energy?

2020
The universe is composed of matter in different forms, and all forms of matter contain energy. The different forms of energy on Earth originate from the Sun — the ultimate energy source. Plants capture light energy from the Sun, and, via the process of photosynthesis, convert it into chemical energy. This stored energy from plants can be harnessed in many ways. For example, eating plant products as food provides energy for our body to function, and burning wood or coal (fossilized plants)...

Free Energy

2019
Free energy—abbreviated as G for the scientist Gibbs who discovered it—is a measurement of useful energy that can be extracted from a reaction to do work. It is the energy in a chemical reaction that is available after entropy is accounted for. Reactions that take in energy are considered endergonic and reactions that release energy are exergonic. Plants carry out endergonic reactions by taking in sunlight and carbon dioxide to produce glucose and oxygen. Animals, in turn, break down the...
FAQs
Photosynthesis captures solar energy and stores it in organic matter, creating biomass that can serve as an energy resource. This biological conversion links sunlight with later production of bioenergy, because the stored chemical energy can be processed rather than used only as plant material. The connection is especially relevant to agriculture and sustainable biomanufacturing.
Microorganisms convert biomass into biogas through anaerobic digestion, providing a biological route for recovering energy from organic material. This process connects microbial activity with bioenergy production and can be integrated into systems that handle biological waste. Its relevance extends to wastewater treatment and agriculture, where available biomass may become an energy-bearing output.
Solar cells and turbines rely on different immediate energy inputs and conversion mechanisms. Solar cells convert light into electricity, whereas turbines convert motion into electricity, including motion associated with wind or moving water. This distinction helps researchers match technology to resource availability, since the useful input is either accessible sunlight or a suitable moving fluid.
Assessment should include the availability of the resource, the land required, and possible ecological effects. For biological systems, these considerations are important when using biomass for energy or linking energy production with agriculture and wastewater treatment. Evaluating them helps determine whether a proposed application can provide useful energy without creating unacceptable environmental pressures.
In wastewater treatment, anaerobic digestion can connect microbial biomass conversion with biogas production. In agriculture, biomass can support bioenergy while remaining part of a broader resource-management system. These applications illustrate how biological materials can contribute to energy supply and waste handling, although land use, resource availability, and ecological effects still require evaluation.
Renewable energy can support sustainable biomanufacturing through biologically stored solar energy, biomass-based bioenergy, or electricity generated from light and motion. These pathways offer different ways to supply energy for biological production systems. Their suitability depends on available resources and environmental considerations, so sustainability requires examining both the energy output and associated land-use or ecological effects.
