Oregon Launching First Solar Highway in the US

Oregon is once again taking the lead with renewable energy by installing the country's first highway solar energy project. The project will consist of a 104 kW solar photovoltaic system that covers 8,000 square feet and produces 112,000 kWh each year. That's 28% of the energy needed to power the project's location, the Interstate 5 and Interstate 205 interchange in Tualatin.

Who's leading the conversation?
This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

Electricity for the interchange will be provided by PGE. The solar panels will come into play by producing electricity during the day, giving the power to the PGE grid, and getting the equivalent amount of power back at night from PGE to power lighting on the highway.

Isn't exaggeration for effect a wonderful thing? This is NOT a solar highway. It is a solar farm at ONE interchange. I hope someone factored in the number of days they really get sun. It DOES rain in Oregon a LOT.

I have checked on solar energy information in Oregon. The current estimates are that solar systems will take at least 25 years before the 'savings' exceeds the cost.

Even so, it's not all about the money. It's less electricity generated by fossil fuels. Sure, it's one location and only a percentage at that. But it's an example to the rest of the country that there are alternatives, and hopefully this design can be improved upon. Probably would work much better in a sunny state, of course.

I agree Tacitus. Every new idea is welcome, every test has some value. Why should the lights lighting highways not be powered by localized solar power, which could feed the grid during the day, use the power during the night. Yes, a test case, yes the title is a little overboard, but why not use the public domain lands next to public highways for power generation? And the more we do it, the better it will become, the cheaper too.

Exaggeration leads to high expectations. High expectations lead to greater disappointment. Greater disappointment leads to less enthusiasm for the expense in the future.
