Using the Philippines as an example, geography renders the answer exceptionally difficult. An archipelago with approximately 7,107 islands, the Philippines does not have a unified national grid. Every island has its own grid — it must stand alone, finding solutions independent of the other islands. Hence, there are as many solutions as there are islands.
Outside of this geography challenge, there are other barriers to conquer:
Conclusion: Achieving 100 percent renewables in the Philippines will be difficult. Advances in new technologies, planning, and huge infrastructure investments are needed. However, social issues may override some of the needed investment.

Is 100 percent renewable energy always achievable or desirable? Yes, but it will not happen overnight and it will differ from location to location. Just like mainline power today, it is a blend of many resources, some being renewable, future power will be a blend, as well.
Our current power consists of coal, nuclear, natural gas, biofuels, wind, hydro and solar. As coal falls victim to EPA standards and issues related to health from emissions to mining pollution, it ultimately has to end and be replaced. Water contamination during mining will cause this to happen to natural gas, as well.
Coal has been subsidized from it's inception for over 100 years and nuclear is no different. The main difference is that nuclear has high cost and no ROI. The cost to build a nuclear facility, produce energy and decommission the facility is larger than most other power sources and cannot exist without extreme subsidies.
As one technology becomes obsolete to another, ompletely renewable dependence is very likely. Since it is already achievable on a small to medium scale, it is just a matter of time. That time may be 10 to 100 years from now, but it will happen and scale up. The key that will assist this, but is not confined to renewables, is power storage, which solves remote and power waste issues and helps people live in what was once an unsuitable area. It will also contribute to efficiencies of current power sources and ultimately help renewables.
