TARGET

We analysed the target we want to reach in terms of number: we want to replace 30% of existing cars in Singapore (500000 cars) with E-vehicles, thus we want 150000 e-vehicles circulating in Singapore in the next 4 years. E-vehicles are only meeting our sustainability criteria if they are powered by renewable and clean energy sources.

How are we going to achieve this?

SOURCE

We decided to select the resource of solar power, as it is the most accessible in a country such as Singapore (very close to the equator, with high temperatures and predominantly good weather)  and because it resulted as the least expensive in comparison with other renewable energy resources such as fuel cells (see research on page 2).

Demand

We calculated the surface of solar panels needed to meet our power demand, in order to meet the target of replacing 30% of existing cars in Singapore which results as 1643835.616 m² .

Placement

We will divide up this huge surface of solar panels in two ways

1. Covering the roofs of existing gas stations (187 stations) in Singapore with solar panels, thus we will be able to place 467500m² of solar panels (28% of solar panel surface needed). This way we reduce the costs of transportation of power and efficiently use the existing infrastructure.
2. The remaining necessary solar panels (72%) will be place on an artificial island near the shore of Singapore, in order to not use up the expensive and scarce surface of the country. Also we have to take into account the price of placing new cables. This will provide the basic infrastructure to generate electricity through solar power, on which the government might wish to expand in the future, by increasing the surface of the artificial solar panels island. Therefore making the generous investment (building island and energy cable placement costs) compelling in the long run.

CHARGING STATIONS

In order to recharge the E-Vehicles we have developed a system that uses existiting gas stations and requires to build new charging stations.

On the existing gas stations we will integrate a battery charging station.

We will build new  charging stations in the rural areas, in order to create a comprehensive infrastructure system.

This will be done following these guidelines (more in detail):

• partly adding the new feature to existing petrol stations, in order to reduce our costs of production and use the existing strategic locations, thus making the charging stations more user-friendly and accessible.
• build new charging stations (with solar panels on the roofs) placed in the strategic and the more rural areas, in order to reach the locations we have found to not be covered properly (such as highways, parking lots etc.)
• we also consider that people have domestic charging stations at home

COST

We expect a cost of 1,442,252,058 for our solar panels. This is a considerable investment but we believe that an innovative and avant-garde country such as Singapore will also be a global example of ground-breaking and sustainable technology, in the interest of our present and  future generations. Reaching further than their market competitors.
