This post, a part of five part series on green building regulation looks at the anatomy of green building regulations identifying three main types of regulations, which are command and control, in other words building codes and such; financial incentives, like tax breaks; and non-financial incentives such as increases in floor to area ratio, building height or density for building green.
This post examines the central role of energy in our lives by posing the hypothetical question the impact that free and unlimited energy would likely have on our world. Of course, as the author points out energy is neither free nor is it unlimited and prices for fossil fuels are destined to rise as emerging economies energy appetites make themselves felt on the market. From a venture capital perspective, it is this type of disruption that makes cleantech a compelling area for investment.
This post reports on the newly announced loan guarantees for the concentrated solar power (CSP) Crescent Dunes Solar Energy Project that is to be built in Nevada. This kind of solar power, because it is paired with a molten salt thermal energy storage capacity has the ability to be a load following generation source that is somewhat insulated from intermittency issues as well. For large concentrated solar thermal energy this decoupling of the energy collection from electricity generation makes a lot of sense, because the molten salt is already being used as the working fluid that captures the sun’s heat.
In the race for the title of the world’s greenest data center a lot of perhaps overly optimistic PUE claims have been made. Power usage effectiveness (PUE) is a measure of how efficiently a computer data center uses its power. While it is a step in the right direction it still fails to capture the complete picture of the data center’s energy and resource efficiency. It goes on to point out ten areas that are not being captured; some of which have significant implications.
This post rebuts the assertion made by Joel Makower that Green Marketing is dead or over. It suggests that green is not being marketed in the best manner; making the point that companies seeking to market their green products and services should focus on selling their products instead of making the consumer feel like their purchases is a cause, charity, public service or a sacrifice that they they need to make.
This post looks at fifteen kinds of utility or grid scale energy storage solutions that are either in wide use or have significant potential to supply the energy storage capacity that will help make the grid both more efficient and more robust. These range from pumped hydro, which is by far the most prevalent form of energy storage at this scale to compressed air, thermal storage, advanced batteries, fuel cells and purely electric storage systems.
This post answers the recently much hyped focus on wind’s variability problem, quantifying it in clear cost terms that put it in perspective. The post helps clarify the differences between energy, capacity and the ancillary services surrounding ensuring capacity and goes on to answer some of the other related problems that have been alleged for wind energy as its penetration level increases.
Three-quarters of large international corporates plan to increase or significantly increase cleantech budgets over the next few years to incorporating clean technologies into existing products to improve environmental performance; entering cleantech segments that are adjacent to existing business units/operations; or create entirely new cleantech-driven product and service offerings, and ultimately new industries.
This post examines the case against subsidies for renewable energies recently made in the WSJ, which opined that renewable energy should focus on the small niche off grid market currently largely served by diesel generators where renewable energy has a clear advantage.
