Important Questions

The United States only began to scale up its use of biofuels around 200039 (see Figure 9.3), so data is scant on how well they can satisfy our need for transportation fuel. At this point, we are mainly relying on studies and models to discover our best options for moving forward. These studies are divided on several important questions, which we will explore in this section. The Potential How Much Can We Really Make The first important question is obvious How much biofuel can we make Estimating...

The Competitive Advantage

Like any emerging energy technology, the evolution of wind power has depended heavily on incentives to level the playing field and encourage its growth, in order to reduce costs and improve performance. Essential wind power incentives are not just monetary. Policy support is crucial, such as setting binding targets for renewable energy generation and carbon emissions removing barriers to deployment and reducing investor risk reforming markets to remove discriminatory access and transmission...

Benefits Of Wind Power

Wind power is primarily a utility-scale technology, with hundreds of turbines arrayed in large wind farms. Wind offers a number of advantages over fossil fuel in powering the grid Wind is a vast, free, and inexhaustible resource. Wind helps reduce our use of the primary fuels for grid power natural gas, coal, and to a lesser extent, petroleum. Recognizing that all fossil fuels will peak within the next 20 years, and skyrocket in cost, it is important that we reduce their consumption as much as...

The Largest Untapped Source Of Energy

Of all forms of energy we use today, marine energy is our largest untapped energy source. Compared to other renewable technologies, it is still very much in its infancy, having received minimal attention and development capital. TABLE 5.1 Energy Density of Renewable Energy Sources 4QQ-6QQ W m2 for a good-to-excellent site, but ranges from 1QQ to 7QQ W m2 2,000 W m2 typical, but ranges from 1,500 to 4,500 W m2 1,000,000 W meter of wave crest length, or 20,000-70,000 W m2 for the best sites Data...
