A LOOK BACK AT WIND, SOLAR, AND GLOBAL ENERGY TRENDS
Renewable energy has grown tremendously over the past decades, and 2008 was a landmark year in several areas of clean energy development. From wind power milestones to solar growth and international energy leadership, there is a lot to learn from past achievements. Here’s a closer look at some of the most interesting renewable energy facts from 2008.
Wind Energy Highlights
In 2008, the United States became the largest producer of wind power in the world. The location of wind turbines is critical for efficiency; a modest 25% increase in wind speed can double the power output of a turbine. Michigan’s Lake Michigan coastline and the Saginaw Bay “thumb” region are among the best areas in the U.S. for wind energy due to consistent and strong winds.
The Vestas V90 turbine, for example, features 148-foot blades atop a 262-foot tower, reaching a total height of 410 feet. Each turbine generates 1.8 megawatts of electricity. In June 2007, T. Boone Pickens, the Texas oil entrepreneur, announced the construction of what would become the world’s largest wind farm in the Texas Panhandle, ultimately projected to include 2,000 turbines generating 4,000 megawatts of power once completed.
Solar Energy Insights
Solar energy was also making significant strides in 2008. Southeastern Michigan averages more than 4.2 hours of clear sunlight per day, and the region’s climate allows solar panels to produce more voltage per sunlight hour than hotter climates such as Southern California, Arizona, or Florida. On a sunny day, each square meter of earth receives about 1,000 watts of energy, and one hour of sunlight could theoretically power the entire planet for a year.
Silicon cells, the primary component of solar panels, can be manufactured from one ton of sand to produce as much electricity as burning 500,000 tons of coal. This highlights the efficiency and potential of solar energy as a sustainable alternative to fossil fuels.
Global Renewable Energy Trends
Internationally, Germany was leading the way, already 50% ahead of its goal to achieve 20% renewable energy by 2020, despite receiving far less sunshine annually than southeastern Michigan. Denmark was projected to produce over 30% of its energy from wind turbines in 2008. These developments showed that investment and planning can make a country a leader in renewable energy, regardless of climate limitations.
Industry Growth in the United States
In 2008, the U.S. Energy Administration reported a 32% increase in renewable energy production compared to the previous year. The solar power industry experienced significant revenue growth, increasing 30% annually from 2000 to 2007. In 2000, solar industry revenue totaled $3.41 billion, and by 2007, it had reached $21.2 billion.
Total solar installations at the end of 2007 included Germany at 3.78 GW, Japan at 1.9 GW, the United States at 903 MW, Spain at 670.4 MW, Italy at 107.5 MW, and South Korea at 84.54 MW. Despite these gains, solar still accounted for just 0.018% of the world’s 2005 energy supply. Consumer interest in solar was growing rapidly, with a survey of 100,000 people showing that 90% believed solar should be an option on all new homes.
Individual Actions for Energy Conservation
Renewable energy isn’t just about large-scale projects; small individual actions make a difference. Americans make up 5% of the world’s population but consume 25% of global resources. Simple changes, such as replacing one standard 60-watt light bulb with an LED, could save 24,184.4 megawatts per day across the United States—equivalent to shutting down one of the country’s largest power plants. These small steps contribute to energy independence and reduce environmental impact.
Energy Policy Developments
In 2008, T. Boone Pickens launched a national campaign to promote a U.S. energy plan aimed at reducing dependence on foreign oil. Energy efficiency and renewable energy adoption were central to the conversation. Denmark’s continued growth in wind energy, producing more than 30% of its power from turbines, served as an international model. At the same time, the U.S. power system required 3.3 kWh of generation to deliver 1 kWh to a household, illustrating the need for efficiency improvements.
The U.S. spent $700 billion annually on foreign oil, with imports rising from 24% in 1972 to 70% by 2008. Policies restricting domestic drilling, including offshore bans, highlighted challenges in energy independence. Meanwhile, countries like China and Mexico continued to expand production without these limitations. Legislative developments in 2008 indicated potential changes, with Congress preparing to allow long-standing offshore drilling moratoriums to expire.
