Good, Perfect, and Real Carbon Targets – Finale

By Jeff Ihnen Energy Rant No Comments

In this week's Energy Rant, we're covering the final segment of good, perfect, and real carbon targets.There are two sources of carbon-free energy. First, we have the category of renewable with wind, solar, hydro, and some geothermal. Second, we have nuclear. Oops – third, we have efficiency and demand management. The electricity market is bizarre to me. Last week I crudely explained how the regional transmission authorities (RTO) and their twins, independent system operators (ISO), balance the grid in real-time. Power supplied must match demand with very tight tolerances of voltage and frequency at all times. The chart below shows…

Good, Perfect, and Real Carbon Targets – Part 3

By Jeff Ihnen Energy Rant No Comments

In this week's Energy Rant, we're covering part three of good, perfect, and real carbon targets.In Part I of this series, we examined how various storage technologies work, their pluses, and minuses. In Part II, we put numbers to generation and storage technologies, including maximum power, duration of discharge (for storage), cost per megawatt and megawatt-hour to build and operate, and a slew of other great stuff. In Part III, we will size up the numbers from Part II to actual grid demand. The objective is to provide scale to see what we would need to pair high percentages of…
