The coral reefs are artificially made, but the whole place is very much ideal for swimming, fishing, and boating.

During low tides, a smaller, more undeveloped island appears and like the rest, is also suitable for fishing and swimming.

With coal-derived electricity, the calculation would include the life cycle from mine to power plant to electric grid.

Experts who study this use the terms “net energy ratio” or “energy returned on energy invested” (EROEI).

For fossil energy generally, the trend is downward despite technological advances in exploration and drilling. Some studies suggest that corn-derived ethanol actually has a negative net energy ratio—that is, more energy than a gallon of ethanol can deliver is used to produce a gallon of ethanol.

Sugarcane-based ethanol has a superior net energy ratio, but it is still low compared to fossil fuels.

Any produced energy resource can be analyzed for its net energy ratio, although the process raises a difficult question: What are the boundaries of consideration?

For example, when tallying the energy required to build a solar photovoltaic panel, what should be included in the accounting?

However, if one will just look around more, they will find that there are other less-known but equally beautiful beach spots in other parts of the Philippines.

In Pagadian, in particular, there are beaches and islands that will make one believe that there is such a thing as a secluded paradise on Earth.

The Muricay Beach is located further away, at 4 kilometers, but the white sands and clear seas more than make up for the distance.

There are also mangrove tracts and seaweed plantations nearby, for those who are interested in such plant specimens.

A society that depends on inexpensive energy to maintain a high standard of living and constant growth faces a predicament—it cannot maintain itself over the long run without high net energy fuels.
