Maybe this is what you had in mind? (one foreach was enough, it seems)

<?
$src = array(
    0 => array('Power Generation' => 'Using the Sun'),
    1 => array('Power Generation' => 'Using the Wind'),
    2 => array('Heating & Cooling' => 'Radiant Slabs'),
    3 => array('Heating & Cooling' => 'Domestic Hot Water'),
);

foreach($src as $items) {
    $k = key($items);
    $v = current($items);
    $result[$k][$v] = 'ACTION_' . strtoupper(end(explode(" ", $v)));
}

?>
<pre>
<?print_r($result)?>>
</pre>
